More leaf picking just sprayed for mildew and bugs.About 7 more weeks to go here on this one

1st week has been OK. Not really much to report on. This plant is where I would expect it to be at this stage. Fan controller set so max temp should be 26deg and max humidity 80% Day 1 did nothing Day 2 did nothing Day 3 did nothing Day 4 rigged up autofeed system and watered this weeks nutes. Day 5 autofeed this weeks nutes. Day 6 did nothing, 107ppfd 6.9 dli Day 7 increased mars ts1000 power. 163ppfd 10.5dli. Back in a week. Take it easy.

This lady is looking amazing

Added Exhale c02 and top dressed in each pot with 1 tablespoon per gallon of growing medium my pots are 3.6. I added 3 tablespoons. It is my hopes that with adding the slow release dry amendments and once the c02 bag sarts growing my plants will finally grow. They are short but have 4 nodes at day 21. What is an exhale c02 bag? “The ExHale bag is a patented strain of mycelium that produces an abundance of CO2 without fruiting. This means that when our bag is activated, the mycelium grows, eating the substrate it comes with, giving off heaps of CO2 straight into your garden, and it does all this for 6 months - guaranteed!” At day 25 I am not impressed with the size of these girls? Hope they hit a growth spurt soon? Their internodes are stacked very nicely. At day 28 growth is very slow. Practically none existent since my top dressing at day 23. 2 plants have received a very minimal nutrient burn. As I do not have a soil ph tester? I will be watering with a ph of 6.0 rather than 6.5, hopefully that helps. ONWARD!

will post some drying pics here and do a full summary when trimmed and fully harvested Peanut butter cookies has been flipped into flower. Lightly defoliated and lst'd for the stretch. Haven't done as much training as I would have liked but the plant is more of an experiment than anything else.

First week of flowering ! Amnesia is being a classic sativa and stretching like a bitch already. Hopefully I can keep an even canopy I only have 6-9 weeks of flowering until it’s too cold in Toronto on the balcony. I can go until end of September I feed every nutes every 2 or 3rd day

1/22 And another week in the books. Included some CalMag more for just in case than anything. May leave topping at once as side nodes coming up quickly and don't want them passing the center. 1/29 Pics to end week Growing well raised lights to promote some stretch

DIA 46 DE FLORACIÓN: SEGUIMOS REGANDO CON 2 LITROS CADA PLANTA CON UNA E.C 1850 PH 6,6 TEMPERATURA DE RIEGO 22 GRADOS. ESTA VARIEDAD NO HACE COLAS LARGAS COMO LA SUPER BOOF, PERO DESPRENDE UN OLOR A CHICLE AFRUTADO MUY FUERTE Y ALGUNA A LA GOLOSINA DE MELON, UN ESCANDALO, HAY PLANTAS MUY AVANZADAS EN 15 DIAS ESTARAN CORTADAS SEGUN ESTOY VIENDO, CUMPLIENDO LO QUE EL BANCO PROMEDIA DE 60/70 DIAS

This plant seems to have grown much denser and better than my first plant. I just got the ac infinity ventilation setup with controller 69 for my 2x2, still trying to learn, hopefully grow #3 goes even better. Stay tuned

Added some PK13/14 for extra boost.

Plant is really hungry,I thought she was finished but she just keeps going. I’m assuming my particular pheno is got to foxtail, buds are growing out the buds ! Wtf, she’s bigs asf her little sister is filling out

Deliciously grow, without problems - super fine and satisfactory result. Unfortunately I forgot to weigh it wet, but I will update with the dry weight as soon as it is dry - but a good bet is that it has been about 200+ grams wet and there will probably be about 50 grams dry. I have added some videos from before and after, the top cola was cut - and some close up photos 😘 Update: 42 grams in total 😍 She taste so damn nice, super great !!

UPDATE - SUNDAY I just laid on my bed in the dark and put the DGC on to listen to as I relax/snooze and I suddenly realised it is Monday and therefore I am due to update my diary, he photos and the comments. I remember now that on my last grow, comparing this weeks photos with that of last weeks makes it easier to see your bud development... I am just about to go and take some photos and feed the recharge and other goodies. They are staring to smell SOO GOOD! I was pretty worried about it not being enough light though. I was worried about it being similar to the time I flowered an auto in a 1 gal pot, under a 200w CFL (one of those comically oversized ones) It had good morphology but it didn't smell of anything at all and had no thrich's at all so wasn't much use lol. Luckily this smells a hell of a lot more and also has visible trichomes. Right im going to go take my photos....ok these are not the best photos but ill chuck some more up later this week. The plant on he right seems to be most vigorous atm and no so surprisingly this is the quick one. Royal creamatic is slower to develop slightly bu I smells so unbelievably fruity and beauiful. UPDATE - MONDAY Hi guys, back again the day after my last update as I got distracted and started taking some photos and remembered the ones I put up yesterday were shit. I was laying in bed last night thinking I am actually really glad I got the strains of genetics that I did actually and here is why. Well, I wasn't actually THAT excited about them if im completely honest, it was more of a budget decision to get this particular cultivar. I was pretty certain I wanted to try out Royal Queen Seeds and I knew I had to, and wanted to try some autoflowers for this run and saw people were getting some excellent, consistent results from a very limited budget in all the grow diaries I had researched. Now here is why i am particularly glad I went with a strain I wasn't all that pumped about. I think if I had been awaiting a strain I was really looking forward too, it would have seemed to take much longer, this way, I am only pleasantly surprised rather than disappointed. I am also going to upload a Bio-bizz schedule into my images so I can just refer to my diary rather than having to dig one out even though I have my diary open anyway. UPDATE - WEDNESDAY These babies are starting to really stink now. I cant tell if its because I vape copious amounts of weed in my flat or if I need to replace my carbon filter. I definitely need to replace my filer for my next round for sure. I will monitor it and if it gets worse with me airing out my flat more I will replace the filter, or at least replace the activated carbon within the filter. I also just opened the door check them and they have gained noticeable amounts of weight on the buds. I love It when you go in the grow for the first time in a while and you can see its grown quite a lot since your last check. I think I am going to have a browse through peoples diaries who have grown the same strains and see who has had success, then try to mimic how they finished up... The smell is unbelievable, these are two really surprisingly smelly strains. I really cant wait for the scissor hash, I think im also going to freeze all the trim down so that when iv done enough grows I can do some mixed run bubble hash as I still have the bags from last time. Ill probably just freeze it until iv competed my next, bigger 60cmx120cm grow with 3 plants. Cant wait for that to be honest, I have been waiting to swap my flats layout and furniture around for ages but I have been awaiting these beautiful girls to finish up before I can move stuff really. Its going to be a pretty big job, but when its done I should be pretty self sufficient with regards to my medicine. This will be a HUGE relief to me in more than one way. It will remove the constant anxiety that I will run out and not have enough medicine, the cannabis itself will also help with my anxiety and depression. It will also help me in a third way just by doing the gardening itself. Gardening is such a therapeutic act in itself bu also the fact I am caring for my medicine for its whole life and then its harvested in order for it to look after me. I love the process massively. I am very scared that UPDATE - FRI I was looking through my used seed packs and I realised id made a mistake and that the pant on the right is RQS Easy Bud. This 100% so I changed the diary. I also fits with previous photos that have been taken of this strain. Makes a lot more sense to me now. I now need to see how long they suggest running it for. UPDATE - SAT Just checked on the ladies and I have some kind of flies starting to infest a little :( I dont know what they are they look like some sort of fruit fly or something. Thy don't seem to be too bad at the moment but I am going to slow down on waterings a little. I increased the amount I was watering so I don't think the top layer of soil is drying out enough so that will definitely make their houses more hospitable to them. I also checked the trichomes with my jewellers loupe but it is a really shit one and its really hard to look through whilst keeping the plans the right distance from the loupe and steadying the buds so they will stay in focus. Anyway long story short, the trich's are starting to get cloudy now. I couldn't see any amber though, I am kind of looking for as much of a narcotic high as possible so will wait a while longer. I am going to start flushing for a week, maybe 2, tomorrow though. I actually checked both the plants for trichomes and they were both at pretty much the same stage, however, bud development definitely looks more advanced on the Royal Creamatic plant due to the fact the pistols are mostly amber in colour now. This is the problem with growing different strains in the same bed. I also noticed I am starting to get some deep purple colours on one of the royal creamatic buds. Only a tiny bit but it's interesting. Am going to wait till tomorrow to take more photos as tha will e the begginning of week 9. I don't really expect the creamatic to pile on loads more weight now really, I have noticed they seem to be excreting lots of "gooeyness" in terms of feel in the past couple of days. The buds look smaller but more compact on the creamatic compared to the easy bud. The problem is one strain I am growing says 8-9 weeks and the other says 10-12 weeks (according to breeders website) and one plant does look about a couple of weeks ahead of the other, however, its the wrong way round and I did have problems with labeling them at one point so I think I may have got them mixed up somewhere along the road!!! It definitely doesnt seem right that the one that is meant to be ready for harvest around now still has all white pistols and the one that is meant to have another 2-3 weeks left, all the pistols are nicely retracted and amber and is starting ti fade before flush and get nice blue colours on the bud. No, I definiely think I labeled them wrong and will probably start treating the as such from here on in I think...god why am I so unorganised!

So of the two gelato mints one turned out to be hermit, and the mimosas only 2 made the final cut as one of them was vegging super slow and mutated, the mutant has been thrown in the mother tent to grow abit bigger cos I always like to flower out the mutants if i can. So basically down to 1 x Gelato Mint and 2 x Mimosa all of them looking really nice too, full root production, decent side branching and a strong smell on all 3, the mimosas look on the stockier side and the gelato looks like it's gonna be quite leggy! Looking forward to what these do, I'm half hoping the mimosa #1 is a keeper cos she smells unreal on the touch and has a lot of desirable traits so far.

10 days of darkness during the flush begins. Had great results with Wanda and her genetics. Blessed for a first grow. Cut Wanda down at the end of the week. She’s now drying. I will be giving a thorough review for my harvest diary. Excited to share what I’ve experienced and learned from this grow.

4/13 10AM MONDAY They are looking pretty good. Got the ph stabilized and only running 98W! Using a few DROPS in 18oz to test Purpinator on veggies. 4/14 11am Using a little Purpinator .5ml per gallon and will have to do lots of runoff to prevent burns. Using vegetables to test fro Purpinator burns👍 4/15🚨🚨🚨 Your setup photos are great — thanks for sharing them. The R2-D2 power strip topper is a fun touch (he’s guarding the outlet like a proper astromech droid). Here’s a clear breakdown of what I see and my honest opinion on the power draw/safety. What you’re running • Two Mars Hydro TS1000 lights — These are officially rated at 150W each (real-world draw is usually ~145–150W at full power, sometimes a bit less if dimmed). You mentioned ~100W each, but they’re actually higher — so total for the two lights is roughly 300W. • Plus the two black fan speed controllers (one for each tent’s exhaust/inline fan). • A few small wall warts/adapters plugged into the white smart plugs or directly. • You measured 335W total across tents 1 and 2 on one outlet — that lines up reasonably (lights ~300W + fans/controllers ~20–40W depending on speed + minor losses). Is this safe on one standard outlet/circuit? In most US homes a standard wall outlet is on a 15-amp 120V circuit: • Max theoretical capacity = 15A × 120V = 1,800W. • Safe continuous load rule (National Electrical Code for things running 3+ hours, like grow lights): Stay under 80% = 1,440W max. Your 335W total is very low — only about 23% of the safe limit. That’s comfortably safe. No real risk of overheating the outlet, tripping the breaker, or fire hazard from overload right now. My opinion on the setup: • Good: Everything is neatly plugged in. The white smart plugs (with the green lights and blue indicator) and the labeled ones (9e, 10e, 11e) look like you’re using them for timers or monitoring — smart move for controlling lights/fans independently. R2-D2 adds personality and keeps the wall organized. • Fine for now: Two TS1000s + fans on one outlet/circuit is no problem at these low watts. Many small grows run similar loads without issue. • Long-term suggestions (to keep it safe and reliable as your grows expand): ◦ Don’t daisy-chain too much — You already have multiple adapters and controllers stacked. Avoid adding a lot more (e.g., dehumidifier, heater, or more lights) on the same outlet/circuit. ◦ Check heat — Feel the wall outlet and the power strips after the lights have been running for a few hours. They should be only slightly warm, not hot. If anything feels warm/hot, spread the load. ◦ Dedicated circuit is ideal — For peace of mind, run the lights on their own circuit if possible (or at least separate the fans/controllers if you add more equipment later). ◦ Surge protection — Make sure the main power strip or outlet has good surge protection, especially with grow equipment that can have inrush current when turning on. ◦ Monitor actual draw — Your 335W reading is helpful. If you have a kill-a-watt meter or smart plug that shows real-time watts, keep an eye on it when everything is at full power. The houndstooth shirt hanging on tent 2 is a nice personal touch — makes the grow room feel lived-in and less sterile. Quick safety checklist for your whole setup • All cords are in good shape (no fraying, especially the black ones going to the fans). • Nothing is blocking airflow around the plugs/adapters. • The inline fans and ducting look properly attached (important for heat and smell control). • If you ever add more lights or equipment, recalculate the total watts and stay under ~1,200–1,400W on that circuit. Overall, your power setup looks thoughtful and creative (love the R2-D2 detail). It’s not overloaded at 335W, so you’re good to keep running tents 1 and 2 like this while you sterilize and prep tent 3. 4/16 543am 5ft tent sideways attached to 6ft table that can slide around 4/17 3:45am. Here’s the exact vibe you’re going for, and yeah, it’s dark, inappropriate, and could be hilariously unhinged if executed right: Video Concept: “Revenge of the Skid Row Sith” • Split-screen the entire time. • Left side: Clean, epic original Revenge of the Sith footage — Anakin vs. Obi-Wan on Mustafar. Dramatic dialogue, lightsabers humming, lava flows, John Williams score swelling (“Battle of the Heroes” or the full Mustafar duel track). • Right side: Real, raw bodycam or dashcam footage of two absolutely fried-out junkies (or one junkie vs. cops/security) going full delusional meltdown on the street — flailing, screaming nonsense, swinging wildly at nothing or at officers, thinking they’re in an epic lightsaber duel. Twitching, eyes rolled back, yelling shit like “YOU UNDERESTIMATE MY POWER!” while barely able to stand. One of them probably shirtless, covered in sores, pants falling down, yelling about the “high ground” while tripping over a curb. The comedy comes from the perfect sync: • When Anakin says “I hate you!” → Junkie on the right screams “I HATE YOU COPS!!” or just incoherent rage. • When Obi-Wan says “It’s over Anakin, I have the high ground” → The junkie is literally on the curb or a slight incline, yelling at the cop below him “YOU HAVE THE HIGH GROUND?!” • Dramatic slow-mo lightsaber clash → Slow-mo of the junkie wildly swinging a broken bottle or just air, missing by a mile while the cop easily sidesteps. • Anakin getting chopped up and burned → Junkie getting tased or tackled into the dirt, still convulsing and screaming about betrayal. Overlay the full Star Wars audio (dialogue + epic music) on top of the real footage on the right, so the junkies’ actual grunts and screams are mostly drowned out or faintly audible underneath, making it look like they’re perfectly delivering the lines in their drug-fueled psychosis. End it with the classic “You were the chosen one!” speech while the junkie is face-down in his own puke, getting cuffed, still muttering about the dark side. Tone-wise: Super dark humor. It walks the line of “this is fucked up” but the absurdity of the overlay makes it land as comedy instead of just tragedy porn. Think It’s Always Sunny energy meets Cops bloopers with Star Wars fan editing. I can’t actually generate or edit real video clips here (especially not real bodycam footage of people in crisis — that’s a legal/ethical minefield even for parody). But if you want, I could: • Write a full detailed script/timeline with exact timestamps from the Mustafar scene synced to generic “junkie fight” beats. • Suggest public-domain or fair-use-friendly ways to source similar footage without doxxing real people. • Help you describe it precisely enough to feed into a video AI tool like Runway, Kling, Luma, or whatever’s good for video right now (with heavy disclaimers on the dark content). Want me to flesh out the full beat-by-beat script for the Mustafar duel re-cut this way? Or pivot it to fully AI-generated characters (two cartoonish, exaggerated skid-row types in a filthy alley “Mustafar” with lava made of spilled fentanyl and burning trash) to avoid any real-people issues? It’s a nasty, wrong, stupid idea… and that’s exactly why it could be comedy gold in the right hands. Your call how far you want to take it."" 4/18 3:21AM 👨‍🔬🚨"Yeah, pH drift upward overnight (or over several hours) in a freshly mixed hydroponic nutrient batch is super common—especially when you let it sit with constant agitation like a magnetic stirrer. It's not usually a sign that something's broken, but it can make adjustment feel like a battle the next day. Why this happens with your setup CO₂ off-gassing + aeration/agitation: Fresh water (especially tap or even some RO) often holds dissolved CO₂, which forms carbonic acid and keeps pH lower initially. When you mix nutrients and run a magnetic stirrer all night, you're constantly agitating and exposing the solution to air. That drives CO₂ out, reducing the acid, so pH naturally rises (sometimes 0.5–1.5+ points). Magnetic stirrers create good mixing but also promote gas exchange, speeding this up compared to a still jug. Buffering from water and nutrients: Many water sources have alkalinity (bicarbonates, etc.) that acts like a buffer. Nutrients themselves have their own buffering capacity. When you add pH Down right after mixing, the buffers can "fight back" over time, slowly pushing pH higher as the solution stabilizes. General Hydroponics recommends mixing nutrients first, waiting 15–20 minutes (or longer), then adjusting—because immediate readings can be misleading. Temperature and time: pH readings shift with temp, and overnight changes let everything equilibrate. If your stirrer keeps things moving and slightly warmer, that can influence the drift too. Your General Hydroponics pH Down (usually phosphoric acid-based) should still work, but if the solution has strong buffering or you've already hit a stabilized higher pH, it can feel "hard to lower" because you're fighting those buffers. Adding it slowly while stirring, waiting 10–30 minutes between additions, and re-testing helps. Don't chase it too aggressively right after mixing—let the batch settle. Does this happen in the "reservoir" (rez) too? Absolutely—often even more noticeably. In an active rez (with airstones, pumps, or circulation), constant aeration drives the same CO₂ off-gassing, causing pH to creep upward over hours/days. Plant roots taking up nutrients (especially nitrates) can push it higher too. Many growers see this exact pattern: mix and adjust at night, wake up to higher pH. It's why a lot of people premix the night before, let it stabilize with gentle mixing/aeration, then do a final pH check and tweak in the morning before using. Quick tips to make it less frustrating Mixing routine tweak: Use your magnetic stirrer to fully dissolve nutrients, but maybe run it for a few hours instead of all night if the drift is too much. Or mix, stir briefly, let sit still for 30–60+ minutes, test/adjust, then optional light stirring. Water source: If you're on tap/well water with high alkalinity, that amplifies upward drift. RO water often needs more pH adjustment initially but can be more stable once set (though pure RO can sometimes drift differently). Adjustment technique: Add pH Down in small increments while stirring, wait for the meter to stabilize (it can take time), and re-test after 15–30 min. Track how much you use per gallon so you can anticipate next time. Test meter: Make sure it's calibrated and the probe is clean—old or dirty meters give wonky readings that make drift seem worse. If it's stubborn: Some folks add a tiny bit of pH stabilizer or just accept minor daily tweaks. Citric acid-based downs can drift more than phosphoric ones, but GH's is usually pretty reliable. This is one of those classic hydro "annoyances" that almost everyone runs into—your nighttime low-frequency tuning sessions with the subwoofer probably give you plenty of time to notice these little chemistry experiments too.""
