Blueberry Muffin – Pheno A | Week 4 Building Momentum Welcome back to another chapter of the 8×8 Adventure, where twelve cultivars are being documented individually from seed to harvest under a strict 12/12-from-seed schedule. Every phenotype follows its own diary, allowing each plant to tell its own story while revealing the subtle genetic differences that make every seed unique. Week 4 has been all about momentum. The explosive growth we witnessed last week has continued, and the entire room is now beginning to transition from a collection of young plants into a true miniature forest. Every morning seems to reveal another noticeable change, with canopies becoming fuller, branches extending further, and the first signs that these plants are preparing for the flowering stretch ahead. One thing that made me smile this week was the environmental reading… 33.3°C and 63% humidity. Apparently the grow room decided to have a thing for the number three. 😄 While 33°C is certainly warmer than I’d normally aim for, the elevated humidity has helped keep the plants comfortable, and despite the warmer conditions the entire room continues to respond beautifully. Sometimes plants remind us that they can be a little more forgiving than we give them credit for—as long as every other parameter remains stable. ⸻ Week 4 Environment 🌡️ Temperature: 33.3°C 💧 Relative Humidity: 63% 💡 PPFD: 700–800 µmol/m²/s 🌱 Medium: Plagron Lightmix ? Growing Method: 12/12 From Seed One interesting development this week is the variation in PPFD across the room. The lighting itself hasn’t changed dramatically—instead, the plants have. Some phenotypes are simply growing faster than others, naturally moving closer to the LEDs and receiving around 800 PPFD, while the shorter plants remain closer to 700 PPFD. It’s another reminder that even under identical conditions, every phenotype follows its own timeline. ⸻ Feeding Strategy As the plants continue accelerating, the feeding program has started to evolve alongside them. Throughout the early weeks, the nutrient solution remained around pH 5.8, encouraging rapid nutrient availability while the young root systems established themselves. Now that those roots have colonized much more of each container, the strategy shifts slightly. This week the nutrient solution gradually moved closer to pH 6.1, while EC increased progressively throughout the week, finishing around EC 1.8. The recipe itself hasn’t changed dramatically. No bottles were suddenly doubled. No drastic increases were made. Instead, the nutrient ratios were simply nudged upward enough to match the plants’ increasing appetite. The difference is subtle inside the reservoir but very noticeable in how vigorously the plants continue to grow. Allowing the pH to drift slightly higher also opens access to a broader range of nutrients within the soil, helping the plants take advantage of their now much more established root systems as demand begins increasing. At this stage, the feeding philosophy remains exactly the same: Feed the plant—not the calendar. ⸻ Blueberry Muffin – Pheno A What can I say… This girl has quietly become one of those plants that instantly catches my attention every time I unzip the tent. Last week I mentioned how she had completely outgrown her slightly awkward beginning. This week she has gone one step further. She looks completely at home. Her overall structure is becoming incredibly balanced, with strong lateral branches beginning to establish themselves while the main stem continues pushing upward with confidence. The internodal spacing remains impressively tight, creating a compact architecture that feels both efficient and elegant. Looking from above, the canopy almost arranges itself. Large fan leaves radiate outward like carefully positioned solar panels, leaving the growing tips exposed without requiring any intervention. Every branch seems to know exactly where it wants to go. The new growth is particularly striking. Bright lime-green leaves emerge from the centre packed with energy before gradually darkening as they mature, creating that beautiful contrast that healthy, fast-growing plants often display. One of my favourite observations this week is just how relaxed she looks. Despite the warmer room temperatures and steadily increasing nutrient strength, there are no signs of stress. Leaves remain flat, praying gently toward the light throughout much of the day, while every new node arrives with confidence. She’s no longer simply growing. She’s beginning to express herself. Each passing day reveals a little more of her personality, and so far that personality can be summed up in one word: Consistency. She isn’t trying to be the tallest. She isn’t trying to grow the fastest. She’s simply building herself into a beautifully proportioned plant, one node at a time. If she continues along this trajectory, I have a feeling she’s going to become something very special by the time flowering is fully underway. ⸻ Looking Ahead The coming week should mark another important transition. With nutrient demand increasing, roots fully established, and several plants beginning to move naturally into higher PPFD levels, growth is expected to accelerate even further. Over the next week I’ll be paying particular attention to: • Stretch progression as flowering begins to establish itself. • Branch strength and canopy development. • Continued response to the higher EC. • Structural differences compared with her sister phenotype. • The first real signs of Blueberry Muffin’s flowering character beginning to emerge. If Week 3 was about proving her potential… Week 4 feels like the week she’s beginning to fulfil it. ⸻ Thank You A huge thank you to everyone following this 8×8 Adventure and taking the time to visit these weekly updates.

08.06.2023 Tag 34 - die Woche regnet es nur und ich habe Probleme die RH zu halten. 65-70% erreicht sie durchschnittlich gerade. - an #2 teste ich agressive Entlaubung "bud focused defoliation" -> bin auf das Ergebnis sehr gespannt 09.06.2023 Tag 35 - Luftfeuchtigkeit bei 65% @ 27°C -> passt eigentlich im VPD und die Pflanze fängt ja gerade erst an zu blühen - Morgen ist Blütewoche 1 <3 - aus dem Dreieck ist irgendwie nix geworden aber ich lass die sich erstmal strecken

Royal haze in the 11th week It's supposed to be a 12 week finisher but think it may go a week longer I've just done a major defoliation to allow all the bud sites to get nice and fat , I had started to cut the nutes down but have put them back upto 4ml a and b per litre again , the 6 photoperiod are on 2ml a and b and 4 ml per litre of rhisotonic , out of the NL , Wedding gelato and zkittles the zkittles has been the best strain so far

12/24/2021 So far only one male has been identified. Glad I just reviewed my video I didn't even notice how light green #3 is, guess I mix her nutes up separately and see if she just hungry? Or naturally lighter than others. All other plants are using coast of Maine mixed into soil (her too) so I'll give her a little mirimichi 901C this week and see what happens. 12/30/2021 Noticing that there is two distinct differences between these girls, color light green and dark green.#1,#3,#8 are light green and #2,#4,#5,#6,#7 Other than that there very much similar growth and node spacing, little differences but very happy with uniformity.Both light green and dark green maintained their magenta petiols, gonna make notes on stem rub notes next week and see how they will compare.

Day 43 - Starting week 7 and she’s looking good. She’s starting to stretch more every day and flowers are starting to fatten up a bit. Gonna continue with the foxfarm feeding schedule. Can’t wait for her to finish! Day 44 - The room is really starting to smell amazing. Just keeping on with the foxfarm nute schedule until she’s ready to be cut in a couple more weeks. Still plenty of fattening and growing to go. Day 45 - No major changes, she’s just chugging along. Gave a feeding of just water today and tomorrow will be the foxfarm feeding. I love her look and the smell starting to really come from her. Day 46 - No major changes, just continuing to fatten, grow and definitely getting really frosty! Day 47 - What can I say? This thing is an amazing grow and smelling amazing. She just growing and fattening each day. Still to early to really look at the trichs but wanted to look anyway. Got a few decent pics and there’s a few cloudy ones in there. Gave her straight pH’d water today and tomorrow and will give another feeding on Saturday. Day 48 - No big changes, just continuing to fatten up. Held off on watering today, she didn’t really drink munch compared to the GC. Will give her an actual “feeding” tomorrow. Day 49 - All is looking good and she’s plumping up each day. Gave her the foxfarm feeding today. Tomorrow starts week 8 so will continue with the feeding schedule until the end. She’s really starting to smell up the room in my house and loving it.

Die Woche war naja so okay die Blätter hängen nicht mehr allerdings sind sie immer noch angefressen ich weiß nicht was es ist ich habe sie jetzt Vor paar Tagen getoppt. Und habe sie auch in die Blüte geschickt allerdings weiß ich nicht ob sie durch ein Experiment habe auch hier Nematoden hinzugefügt weil wir irgendwelche Würmer im Boden entdeckt haben beziehungsweise Larven von den Fliegen die überall rum fliegen. Jetzt abwarten wenigstens stehen die Blätter wieder schön ganze wächst weiter das war wohl viel Stress mit in die Blüte schicken und Toppen in einer Woche aber abwarten. Ich hoffe dass die Blätter so sind wegen den Fliegen und nicht wegen über Besserung allerdings habe ich sie auch austrocknen lassen und jetzt noch mal neu gegossen mit den Nematoden bis nächste Woche

Alright growers 🙏🏻 So this is the start of week 2 of flowering these girls - all I can say is this time around has been a nightmare of problems right and left ha. I’m now struggling to keep temps down and RH down, I got a small dehumidifier in there 1.7litres to help out. But these girls are starting to take shape now I done a slight defoliation on the lowers to help air circulation. All is looking well and hopefully get to see some progress soon. I’ve not really taken much care or notice of the clones it took of the - Buddha blue cheese Exodus cheese Got these to stickers mixed up - rs11 & platchata (in-house genetics) So I’ve potted them into small pots Few of the auto strains I had I got rid of a couple of them as they were slow growth properly due to stress’s. A couple of them are still going okay but definitely not dense buds at all mostly airy so not a fan at growing these compared to photoperiods. Happy growing guys 👌🏻✌️🏻🍁

Just drying first day 🙏

Sorry I missed a few weeks was outta town and not able to update! Things hav been going well! Took some time for em to start growing fast! But they are growing fast! Gonna need some rest from the topping and training from the bud clips. I think I got the manifold line down for all the plants! The og kush I accidentally fimmed it was dramatic lol but made it thru and still growing strong! Makes me laugh fim stands for “fuck I missed” but all this is trial and error for me! Any advice is appreciated! “ happy growing”

Everything is working well, the white flyes are extinct for now. Got a bit of spotting here and here that i presume is from the neem but not sure. Runoff is getting out in the same value as the input, and PH is not dropping, but I suspect to have a bit of salt buildup. I have diled a bit back on the base for 2ml/l, leaf color is great. Have to travel soon so I’m putting up a irrigation sistem to help out in this 7days that i will be away...

Las 4 nenas del scrog iniciaron con el ciclo 12/12 el día 05/11/2021: están siendo alimentadas con advanced nutrients(dosis indicadas en la foto de la tabla). Las 2 nenas en macetas de 30LT iniciaron el ciclo 12/12 el día 26/12/2021: por el momento están siendo alimentadas con advanced nutrients(dosis indicadas en la foto de la tabla)

Did a light feed flush on Saturday 10-11 and started her on 12/12. Got her first Bloom feed on 10-14. Shes already moved, from 3 days to every other for water. also did a light foliar spray of epson salts. the day she flipped, so it wouldnt affect the sites. after 2 days, she already showing hairs in her bud sites. much quicker than my first time. it took a week. im happy with her space, hopefully don't have to do much till, day 21ish! Oh and Silly kitty! 😻😹

Eccoci qui... Finalmente dopo uno stop per il lavoro torno ad aggiornare il diario con il capitolo finale... Non ci sono parole una genetica che mi ha lasciato spiazzato per la compatezza delle cime da curate (vedrete a breve) davvero WOW Grazie a @Xpertnutrients per la collab e a tutti per il supporto🔥🌲❤️ NE VERRANNO DELLE BELLE

Week 7 Flower- Day 51 flw / Day 107 of cycle Black gum is my little favorite I would say 😅 She is smelling really good, kind of strawberry bubblegum in the end.. it’s a pitty it did not grow much. I started feeding only water this week and I believe she is gonna go 2 more weeks till haverst. Let’s gooo 🔥🔥🔥

Well it's almost time, buds have got so heavy the plants struggling to support them :) The smell on these AK47 is intense. They've been on plain water for a couple of weeks with a little calmag added. Looking forward to harvest. Thanks for watching, I appreciate it.

Finally I was back. This a massive success in my opinion since she grew completely unattended from seedling stage to harvest. I kept my fan off all the time since I was abroad, this caused formation of mold in the main branch (probably Botyris). I removed it and I lost not more than 8grams I would say. I couldn't do any flushing though I have to say she didn't receive a lot of nuts (the soil was 50% soil from a previous grow and 50% organic compost. Chopping next week
