Blueberry Muffin – Pheno A | Week 3 The Awkward Start Is Officially Behind Her Welcome back to another week of the 8×8 Adventure, where twelve cultivars are being documented individually from seed to harvest under a strict 12/12-from-seed schedule. Each phenotype receives its own diary so development can be followed independently, allowing subtle differences in structure, vigor, and expression to reveal themselves over time. This week marked one of the most significant environmental changes since the project began. The lighting intensity was increased from approximately 370 µmol/m²/s PPFD to 700 µmol/m²/s PPFD at canopy level. Rather than easing into the increase slowly, the decision was made to provide the plants with a much stronger light source and observe their response carefully. The result? They loved it. Alongside the increase in light intensity, feeding volumes and nutrient strength were also adjusted to support the accelerating growth rate. Week 3 Environment 🌡️ Temperature: 27.4°C 💧 Relative Humidity: 55% 💡 PPFD: ~700 µmol/m²/s 🌱 Medium: Plagron Lightmix ? Growing Method: 12/12 From Seed 💦 Water Consumption: ~0.9–1.2L per day Feeding Schedule Days 18 * EC 1.0 * pH 5.99–6.0 * Approximately 1L Day 21 * EC 1.3 * pH 6.0 * Approximately 1.2L As always, the objective remains simple: provide stable conditions, observe carefully, and allow each plant to express its own personality. ⸻ Blueberry Muffin Pheno A I have to admit, this one is becoming increasingly enjoyable to watch. If you’ve been following this diary since germination, you’ll remember that this phenotype showed a few odd characteristics during its earliest days. The first leaves arrived with a slightly unusual appearance and briefly raised some questions about how she would develop. Fast forward to Week 3 and those concerns feel very distant. The new growth is absolutely beautiful. Leaf structure has normalized completely, color is rich and healthy, and the overall plant has developed into a compact, vigorous young specimen with excellent symmetry throughout the canopy. One of the first things that stands out is the internodal spacing. Despite the substantial increase in PPFD, the plant continues to stack nodes tightly, creating a dense structure that suggests strong genetic vigor and efficient use of the available light. Rather than stretching upward, she is focusing her energy on building a solid framework. Looking closely at the canopy, the branching is already beginning to establish itself naturally. Side shoots are emerging confidently and there is a clear sense that this plant is preparing for the next stage of development rather than simply adding height. At this point she is already pushing into the seventh to eighth node range, which is impressive considering the timeline and the 12/12-from-seed approach being used throughout the project. The foliage itself is another highlight. Large, healthy fan leaves radiate outward from the center of the plant, creating a broad solar panel that is capturing every available photon. Color remains a lush, vibrant green from top to bottom, with no signs of stress despite the environmental changes introduced this week. The newest growth is particularly exciting. The central growth tip is expanding rapidly and showing the kind of vigor that makes a grower eager to check on the plant every day. There is a feeling that this phenotype is only beginning to reveal what it has planned. For now, she sits comfortably among the stronger performers in the room, combining healthy structure, excellent color, strong branching, and compact growth habits into a very promising package. Most importantly, she simply looks happy. And happy plants tend to tell the best stories. ⸻ Looking Ahead The coming week should be very revealing. With the root zone continuing to expand, nutrient levels increased, and lighting now operating at a much higher intensity, the pace of development is expected to accelerate noticeably. The main points of interest moving forward will be: * Continued internodal spacing * Branch development * Overall vigor compared to her sister phenotype * Early indications of Blueberry Muffin structural traits * Response to the elevated PPFD levels If this week’s momentum continues, Pheno A could become one of the more interesting plants to follow as the project progresses. ⸻ Thank You A huge thank you to everyone following along and supporting these diaries week after week. Thank you to the entire GrowDiaries community for creating a place where growers from around the world can learn, share, and improve together. Thank you to Plagron for the nutrients and cultivation support that help power this project. Thank you to Zamnesia for providing the genetics, equipment, and the opportunity to explore these cultivars from seed to harvest. And thank you to every grower who takes the time to stop by, leave a comment, share advice, or simply follow the journey. The adventure continues. 🌱💚🍇?Growers Love and see you next week.

Die terps werden immer intensiver, vor allem die FrostBanger kommt so süß daher. Alle buds sind ordentlich fest und haben eine sehr schöne Größe. Zwei bis drei Wochen werden sie noch brauchen, die Apple-Fritter vorne rechts braucht eher noch 4-5 Wochen, ist halt keine Fastbuds, der Unterschied ist schon sehr deutlich zu erkennen. The terpenes are getting more and more intense, especially the FrostBanger, which is so sweet. All the buds are nice and firm and a great size. They'll need another two to three weeks, the Apple Fritter in the front right probably needs four to five weeks – it's not a Fastbuds, after all; the difference is already very noticeable.

End of Week 6, Day 42 and all is fine. Been slowly adjusting the light schedule this week, getting ready for the switch to 12-12. Currently at 15-9, will be 14-10 on Saturday, 13-11 on Sunday and finally 12-12 on Monday March 11. She is a little smaller than the other 2 Purple Kush. First time running both strains so don’t know what’s the norm. Getting a little worried about the crowding in the 39” x 48” x 72” tent with 4 plants in there. Wish me luck 😎

Auto Opium is bulking, and filling in. She is starting to get a aroma going good. She should finish up in 2 to 3 weeks. Everything is going okay. I plan to sterilize the room once it is clear. Nothing more to report at the moment. Thank you Medic Grow, and Divine Seeds. 🤜🏻🤛🏻🌱🌱🌱 Thank you grow diaries community for the 👇likes👇, follows, comments, and subscriptions on my YouTube channel👇. ❄️🌱🍻 Happy Growing 🌱🌱🌱 https://youtube.com/channel/UCAhN7yRzWLpcaRHhMIQ7X4g

Venga familia que ya viene la cosecha de esta Amaretto Tarmac de Seedstockers, que ganas que tenia ya de darles machetazo. No veas que pinta que tienen estas plantas. Las flores aparte se ven bien resinosas, y tienen un color rosado púrpura brutal. a sido una genética con la que disfruté mucho cultivarla, no es complicada de cultivarla pero merece la pena si eres cultivador con experiencia las flores serán increíbles. Hasta aquí es todo , espero que lo disfrutéis, buenos humos 💨💨.

8/8 Rained all night. Still raining today and the forecast says it will continue throughout the day until midnight. It's come down heavy at times but for the most part it's a rain that plants like. Defoliated a couple leaves but nothing really needed it. Without a trellis or my tarps up the grow bags seem to dry out incredibly fast so I need to watch that. It's also "toughened" up the plant wants. I've seen them blowing straight sideways and they were fine. I do need to find that four lined plant bug and spray BT after the rain. Plants lovedcthe nutes. I might feed a little later today or tomorrow. I've got a few things to do but I'll keep this updated. Went over and defoliated ANYTHING that needed it and combed through every plant during a pause in the storm. Then I shook them all off and did a video. This is by far the healthiest crop I've grown! I think they can handle more nutes too so I'm going to up it next feed. Still seeing stptadoc chunks missing and random pillar damage. BT will handle it. It's just so minor I'm not even sure if it should be addressed that way. I've had pretty good luck just looking for them and picking them off. 8/9 Cannabis can grow an inch or two in a day and it definitely has been! The rain has finally stopped. I went and shook all my plants off. I'm going to check and see the last time I fed and try to get a feeding schedule created that won't cause lockout. That's been a problem in the past. I've defoliated a lot of leaves lately but EVERYTHING is looking amazing. Extremely healthy. I DO need to spray BT for the pillars and I need to move that one plant back. I keep forgetting to grab the little wheels I need to make a platform. There are other ways I could do it I guess. I'll keep this updated. No damage from the storm and I went through and defoliated before and after. Forgot to upload shit and now I'm back home with this shitty internet connection. I'm trying to upload this video but we'll see. It's at like 32%. I did a full workout and came back to find this at 77% lol. I need to remember to upload things when I'm not in the middle of the woods. UPDATE: Checked on things and did a video. Need to feed, apply bt and secure individual branches before flowering increases 8/10 LOOKS to be a beautiful day. Growbags are heavy as hell and wet on the bottom. I ALMOST fed today and I still might. The pp in the 10 seems to have leeched a lot of nutes. That and a giant blueberry cheese are the only places I'm seeing a deficiency and I want to keep it simply. I also need to put a trellis up apply BT. also if I'm going to move things around I've got to do it before I put up flowering supports. It's harder to move stuff when it's wet. I'll keep this updated. The girls look fantastic. UPDATE: Went and trellised two of my plants. I was going to feed today but decided to wait until the next time I water. I'm only seeing deficiencies on the phrple punch in the ten and the GIANT blueberry cheese that I watered the most. Bags were heavy as hell this morning but I bet I'll need to water tomorrow. We'll see. Hahaha wow. I'm trying to upload a video but even my tough as fuck plants might have some difficulty in torrential rains like this. Wow. That's all I can say. I'll either go check and shake them off tonight or if it keeps it up I'll wait until morning I guess. What a shit show 8/11 WOW. That's probably the hardest I've ever seen it rain. Got to the grow this morning and found NO damage. It's super sunny amd windy so the bags will probably dry out. I think it's suppised to rain again Sunday. I definitely haven't had to water that's for sure. Nothing was even bent over this morning. The blue cheese I didn't fim or top (I wanted to see gow it grew naturally) pop ka was bent down a little bit but not much considering the pounding it got. You can see on the videos. Since bags were saturated I didn't need to water before I fed. I fed 1.25 pints to every plant. I gave the fifty 2.5 pints and the purple punch in the 10 got closer to a pint. I want to start out slow with nutes as I'm nor seeing many deficiencies. I may fuck around today and put some more trellises up seeing this wind bur when flower comes I can just put my tarp up. I'll update as I go. UPDATE: WENT BACK OVER BECAUSE THE WIND WAS WHIPPING LIKE CRAZY AND TREES WERE DOWN. I SANITIZED ALL MY TRELLISING AND HORIZONTALLY TRELLISED TWO 10TH PLANETS IN FRONT AND VERYICAL TRELLISED THE THIRD. HORIZONTAL TRELLISED THE PURPL WE PUNCH IN THE 10 AND VERTICAL TRELLISED THE BLUE CHEESE IN THE 50 AND THE 10TH PLANET IN THE MIDDLE OF THE CAGE. GLAD I GOT THIS DONE. NOW I JUST NEED TO SPRAY BT AND I'LL FEEL CAUGHT UP. 8/12 Got my supports up and ready now I've just got to find the time to give the girls an application of BT. I've done a pretty good job with manual removal thus far. Bags are over watered. It's Rained so hard and so often that the bags have stayed drenched. Luckily this ridiculous wind has been drying my grow bags out relatively fast. I'm hoping that will be the case today. They're starting to dry out but it's supposed to rain tonight and I think tomorrow. Bright and sunny right now. These are some resilient plants. They seemed to like the liquid kool bloom. I noticed (barely noticeable but I was looking for it) a SLIGHT color change at the very TIPS of a few leaves on a plant but not enough to consider it burn. I will monitor but I think ive got a pretty good feeding regimen. I plan to use as little as I can get away with. I'll keep this updated. UPDATE: WENT TO CHECK ON PLANTS AS I GOT "THAT FEELING". EVERYTHING WAS LOOKING GREAT BUT THEN I WENT AND LIFTED MY DRY 22GALS OF SOIL AND COMPATED IT TO MY 20S AND LIKE I THOUGHT THE WIND HAD DRIED THEM OUT. I CANT BELIEVE HOW QUICK THEY DRY OUT. I GAVE EVERYTHING 1.5 GALLONS AT LEAST EXCEPT FOR THE 10 WHICH I GAVE A LITTLE LESS THAN A GALLON. I GAVE THE 50 A LITTLE OVER 2 GALLONS AND I DISNT NOTICE RUNOFF. I HAD MORE WATER MIXED UP IM THINKING I SHOULDVE GIVEN IT ANOTHER GALLON. OH WELL ITS SUPPISED TO RAIN A LITTLE TONIGHT AND THEN TOMORROW. I HAVEN'T WAYERED IN LIKE A WEEK SO I PROBABLY SHOULD'VE GIVEN THE WHOLE 2 GALLONS. THEY GOT DAMN CLOSE THOUGH. 8/13 Rained like hell last night. Oh course it did. Doesn't really matter though. I had to water. I thibk the last time "I" watered was lime a week ago. My bags were dry. Plants weren't drooping and they might've been ok but I've under-watered twice already to the point they drooped right over dead looking and I wasn't going to do that again. Plants seem to love the nutes I gave. Keeping the tarps off and allowing the wind through and having my bags on pallets has really saved me this year. Everyone else is bitching about the rain and lack of sun but things are going great for me knock on wood. I'm not 'in the ground' though so that probably has something to do with it. I just need to check my plants multiple times a day. These plants are getting massive. The cage is at least 8ft tall and the biggest one is about to the top now. Almost as wide too. 8/14 I forgot to write the entry but I uploaded some pics from this morning. They were wet from the storm but I went back over and took video that's like two and a half minutes plus I took some pictures. I pulled the cage out but I need to undue one of the lathes and pull it forward. I also need to apply BT. Plants seem to be aggressively flowering (some more than others) so it's a real exciting time. I went over this afternoon and everything looked fantastic. I'll try to upload a few pictures but the video will have to wait. Didn't rain today and my bags sry out quick so I'm sure they'll be fine even if it rains. I did notice that the two plants I watered most including the smallest container seem lighter in color. IT might hust be the transition to flower but u think I need to increase feed. On the 10th planet's they are green as can be and have that SLIGHT little almost unnoticeable part you really have to look for on the tips that means it's getting its nutes but it's not burnt. I believe I'm going to have to make feeding schedules for each strain

This week since Monday most of the pistils (little hairs) have turned from white to brown and orange. I continue to remove leaves that are obstructing the flowers. When I look through the magnifying glass the trichomes are some 60% clear, 40% cloudy, 0% amber. The goal is to harvest with these values in the trichomes: 0% clear 90% cloudy 10% amber

Decent grow. A lil disappointed that I fucked the left most plant. It didn’t go completely to waste, gave it to a friend who wants to make hash from it. The other buds were quite nice though. Like I said, decent for the price.

Parece que tienen una deficiencia de potasio ,hoy he regado con Monster bloom y floración de boom nutrients y Candy boom ,el problema ha sido que en la segunda semana se me pusieron las hojas amarillas y pensaba que era nitrógeno ,añadí nitrógeno y era potasio la cagué !! Ahora no se si es falta de potasio o la he torrado con nitrógeno y tengo que lavar raíces ,que opinais

Annnnnnnnnd FLIP. Switched to flowering 2 days ago. they are growing unbelievably fast right now its incredible. She is one healthy flourishing plant thats for sure!!! So she has kind of blended in with her friends for the time being but soon the flowers will distinguish them again. I'm expecting some nice thick flowers from this lady. Very excited to see how flowering goes with my first seeds from sweet seeds! Will tuck and do and do a big defoil for the last time this week and then let the ladies basically do their thing for the next 2 months. I proactively trimmed off all the lower nodes earlier so the under canopy is basically already clear. The only odd thing I did notice was all the ladies seem to have smaller main "trunks" than normal yet they seem extremely healthy. ah well lets see how flowering goes!!

Overview of the whole grow so far.. everything is looking healthy no signs of mold pest resistance is there with the help of the dragonflies and natural ladybugs and other predators in the garden including garter snakes.. the snakes just coil around the trunk of the trees.. Everyday the odor of the garden grows stronger skunky and sweeter.. Cinderella 99 has the strongest odor and most fragrant buds, followed by the Purple Haze, then the Strawberry Cough then the Afghan hash plant and then DJ Short Blueberry but to be fair the blueberry and the Afghan we're late bloomers as we all know

Hola amigos! Buenos humos a todos! 🌊🤙 La semana anterior no hice actualización, pero he estado haciendo lavado de raíz casi en todas las plantas. La humedad acá es todo un reto, 3 ventiladores, 1 deshumidificador y 1 extractor no es suficiente para 1.5m2. No hay forma de bajar del 70%. Hasta arroz he puesto en la base de las macetas. He tenido nuevamente problemas con botrytis y tuve que cortar algunas colas o parte de ellas. Esto es lo peor que puede pasar ya en la última semana. También tuve otro problema, pues a pesar de nunca haber tenido un macho en casa, ni haber detectado alguna hermafrodita, una de las AK47 apareció polinizada y está echando semillas (ya al final de la floración) . Tuve que cortar varias ramas y flores para detener esa producción y así la planta termine de madurar. No sé cómo irá a quedar esa marihuana con ese problema, pero por el tiempo que queda, no creo que termine de formar por completo las semillas. Otra opción pudo ser estrés por exceso de PK o por exceso de calor (más de 27C). Leí que esta sepa es propensa a crear flores macho por estas causas. Todo lo demás anda bien. Les dejo unas pocas fotos y un video rápido. Hoy estoy limpiando un poco y esta un poco desordenado.
