💎 Black Diamond Auto by Zamnesia – Pheno B | Week 1 Flower | Grace in Every Stretch Some phenotypes command attention through explosive growth. Others quietly impress by doing everything right. Black Diamond Auto Pheno B belongs firmly in the second category. As she enters her first week of flowering, she continues to display remarkable balance, combining vigorous vertical growth with an elegant, open structure that allows every developing flower site to breathe and receive excellent light. While her sister has become one of the stars of the room, Pheno B is proving that consistency can be just as exciting. One of the greatest joys of growing multiple phenotypes is watching identical genetics express themselves in unique ways. Every plant in this project shares the same environment, nutrition, lighting, and training techniques, yet each develops its own architecture and personality. This grow also continues my favourite challenge: 12/12 From Seed. From the moment each seedling emerged, they have grown under a flowering light cycle, allowing every phenotype to reveal its natural strategy for stretch, structure, and flower production without an extended vegetative period. Week by week, Black Diamond Pheno B is proving just how well this technique can work. 🌱 Environment Another stable week inside the flowering room has allowed the plant to focus entirely on healthy development. 🌡️ Day Temperature: 29°C 🌙 Night Temperature: 25°C 💧 Relative Humidity: 60% 🥤 Nutrient Solution Temperature: 21°C 🌱 Root Zone Temperature: 21°C ☀️ Light Schedule: 12/12 🌬️ CO₂: 636 ppm I've always believed that consistency wins over perfection. Stable temperatures, healthy root conditions, reliable irrigation, and continuous airflow allow the plant to dedicate its energy to growth rather than constantly adapting to changing environmental conditions. That stability continues to pay dividends. 🌿 Training & Canopy Management The training philosophy remains exactly the same. Gentle Low Stress Training continues shaping the canopy while regular leaf tucking helps expose developing flowering sites without removing healthy foliage. No defoliation has been necessary. Instead of taking leaves away, I simply reposition the larger fan leaves whenever they begin shading future bud sites. This keeps the canopy open while allowing every healthy leaf to continue acting as a solar panel, producing the energy the plant will soon need for building flowers. Sometimes the smallest adjustments create the biggest long-term results. 🌾 Feeding Program As flowering becomes established, the nutrition program continues supporting both the final stretch and the beginning of flower development. Current feeding includes: • Plagron Terra Bloom — supplying phosphorus and potassium as flower production accelerates. • Plagron Power Buds — supporting the hormonal transition into flowering and encouraging the formation of additional bud sites. • Plagron Sugar Royal — promoting terpene and resin development from the earliest flowering stages. • Plagron Pure Zym — improving nutrient availability by breaking down old organic material around the root zone. • Plagron Green Sensation — introducing a balanced flowering stimulant to support early bud formation while preparing the plant for the weeks ahead. The feeding program remains well balanced, with healthy dark-green foliage, vigorous growth, and no visible signs of nutrient stress. When a plant looks this comfortable, there's little reason to change what's already working. 💎 Phenotype Spotlight Black Diamond Pheno B has developed into one of the most elegant plants in the entire room. Now standing around 120 cm, she has become one of the tallest phenotypes in the project, stretching confidently while maintaining excellent structural balance. Her internodal spacing is slightly more open than some of the other plants, creating a naturally airy canopy that should become a real advantage later in flowering by improving both airflow and light penetration. Fresh white pistils are appearing across every branch, and flower sites are forming consistently from the lower nodes all the way to the main apex. Rather than rushing to produce dense flowers immediately, she seems focused on building a long, evenly spaced framework that promises multiple productive colas over the coming weeks. What stands out most is how effortless her growth appears. Despite her height, the stem remains thick and sturdy, the branches are well positioned, and every part of the plant feels balanced. She has responded beautifully to gentle LST, opening naturally without ever showing signs of stress. One thing has become increasingly clear throughout this project: Zamnesia's Black Diamond genetics are proving remarkably stable. Standing beside her sister, the similarities are impossible to ignore. Both phenotypes share outstanding vigor, beautiful structure, and excellent health, while still expressing enough individuality to make documenting each one worthwhile. Sometimes the best genetics don't create identical plants—they create consistently exceptional ones. 🔭 Looking Ahead Over the coming week I expect the flowering stretch to begin slowing as more energy shifts toward flower production. The small clusters already forming along every branch should start connecting together, gradually transforming this elegant framework into long, well-defined colas. Gentle leaf tucking will continue helping maintain an even canopy while preserving every healthy fan leaf that contributes to photosynthesis. If she continues developing at this pace, she's well on her way to becoming one of the standout performers in the room. The framework is complete. The roots are thriving. Now it's time for the flowers to take over. A huge thank you once again to Zamnesia for providing these fantastic Black Diamond genetics, and to Plagron for the nutrient line that continues supporting every stage of this journey. I'd also like to thank the incredible GrowDiaries community for following these phenotype journals week after week. Your encouragement, questions, and shared passion are what make documenting each individual plant such a rewarding experience. Watching sisters grow side by side while expressing their own unique personalities is one of the greatest pleasures of every grow. Until next week... Growers love and Happy Growing! 🌱💚

Bueno entramos en semana 3 de flora... pasaremos usar pl booster y esperemos poder pasar led antes que acabe esté cultivo. El calor lo hace insoportable para las plantas están bastante resentidas a ver que tal sale! Salut y força al canut farmers!🔥

semana de crecimiento de tricomas, ademas las flores presentan un crecimiento muy bueno, ya están madurando de verdad, el próximo cultivo lo documentaré con fotos mas claras, he aprendido mucho de tenerlas en hidroponia, me gusta y lo voy a seguir usando y explotando

Nice growth!! She's doing well.

So this grow came to a finshed but I had a. Few issues that’s held me up from finishing up the diary, but in due time I will reupload it all in order soon. But over all I will also update with a final weigh in of each strain produced so stay tuned 🤙🏻🔥

🙏 Big thanks to Plagron and Zamnesia for putting on the Eternity Grow Cup 2025. This kind of platform means a lot to the community. The chance to push our grows, test out new techniques, and connect with other cultivators from all over has been inspiring. Appreciate the love and effort that went into making this event happen! Hope everyone enjoyed looking over my shoulder on this grow and best of luck to all participants! REVIEW - Runtz (fem., photo.) from Zamnesia: ⬛⬛⬛⬛⬛⬛⬛⬛⬜⬜ The seeds from Zamnesia germinated rapidly, rooted strongly, went wild in veg, and produced an ample amount of high-quality medicinal flower. The diary speaks for itself on that front so this space will be more of a phenotype review. The plants were labelled A, B, and C from left to right respectively in photos. A and B were the 'clasicaly-appearing' sativa-esque leaves while C was the more 'indica-appearing' phenotype. Although A and B appear the same qualitatively, they did produce substantially different amounts of flower (despite their DLI being near max out for the entire tent footprint without supplementing CO2, so I do not think just being in the middle attributed to this). Past their different yields, A and B also have vastly different profiles. A is a classic gelato/ice cream cooler/Z terps, and my personal favorite of the plants (wish I had taken a clone of this one instead). B is the most on point for what I think of with Runtz, classic Z terps but with a slight tropical/rotten/sweetness to it. C had the misfortune of being ready to chop a little earlier than the other girls so her profile is mostly just spicey kush now. I did observe intersex flower sites but given the entire context of the diary and how the plants performed, I have to assume it was user error. No pollination observed in any of the flowers, as zero additional intersex sites occurred. The distinction between A, B and C is what I would expect from a typical F1 cannabis seed. I do not enjoy growing from seed much but these girls were manageable. Add to that the relative stability of the genetics for a Runtz recreation, and well, these are good quality beans for a great price. Not only is Zamnesia responsive and available, their confidence speaks volumes. How many vendors would have an in-house Runtz, knowing how much of a genetic-gravity-well it is in, and be confident enough to let ~200 randos grow it and show it? REVIEW - Green Sensation from Plagron: ⬛⬛⬛⬛⬛⬛⬛⬛⬜⬜ I enjoyed using the green sensation, the NPK values on it make it versatile in application and a power-house in flower. I can't say I noticed anything better or dramatically improved, although comparing to Heavy 16 and asking for a marked improvement is big ask in my opinion. What I was able to do was seamlessly integrate the Green Sensation into my current routine. The additive stayed homogenous, was easily introduced into solutions with no adverse impact to the water contents or pH. Most importantly, the plants enjoyed the additive and it did accomplish the main goal of being able to wane off your primary line. In this respect, by using Green Sensation I was able to save resources by lowering my Heavy 16 inputs across the board approximately 50% and supplementing with Plagron's Green Sensation.

Hey Cannafam, Well its been a fairly good week for my gal, weve had a few days of light rain but nothing to harsh,not enough to bring the snails out and this is probably the first week that shes not been attacked by a pest of some kind. Most days have been hot and sunny and its still been fairly warm at night as well, thankfully the temp drop has been enough to start bringing out the purple colours further. They start in the middle of the plant and are slowly spreading out 😊💜 Shes also been thirsty and has two feeds this week with a watering every other day. Smell is ramping up now and the lovely forest fruits can be smelt when you brush a sugar leaf. Bud development is slow and steady and shes starting to frost up now as well 😊 Overall shes doing well and the good weather is set to continue which im pleased about! Thats all from me for now, take care my friends 💜💜💜

18/09/2023 I'm very eager to harvest, especially since they all seem ready for harvest except for number 3. Like in the previous weeks, I'm hardly cutting anything, just removing the yellow/brown leaves that come off easily when I pull on them. Regardless, I think I'll harvest next week because the small buds in the lowers parts of the plant and not just the sugar leaves are starting to turn yellow/brown. I forgot to take a picture of the main cola of number 2. I still can't upload great quality vidéo idk why sorry for that ridiculous amount of pixel in the video. 20/09/2023 I was watching a guy on Youtube talking about harvesting when this idea (See the last picture) came to me... I feel so DUMB for not doing this WHEN I did the LST... SEVEN WEEKS AGO, and right now I would not be struggling with the little delay on number 3.

Defoliated and trimmed lower fluff from The plant day 20 flower , Lots of air and light can now get to the plant and hopefully grow some nice buds

Week 2 Report: The White OG - The Solo Survivor Shines 🌟 She may be the solo survivor, but The White OG is already proving she’s a beauty in the making! With her third set of leaves emerging, she’s entering Week 2 of veg and starting to find her stride. This week has been all about supporting her early growth with balanced nutrition, a perfect environment, and plenty of love. Let’s dive into why Week 2 is such a game-changer and how the Aptus Holland line is setting her up for success. Why Week 2 Veg Is Vital 🌱 This is a pivotal time for any grow. The foundation laid in Week 2 determines how well your plant will perform later. It’s about encouraging root development, strengthening the stem, and building the resilience she’ll need for the big stages ahead. The third set of leaves is a sign that she’s transitioning from her seedling phase into a true vegging plant, which means she’s ready for a little extra care in the form of feeding. Feeding with Aptus Holland: A Total Game-Changer This week, I introduced the Aptus Holland organic-mineral line, and wow—this stuff is incredible! It combines the best of organic and mineral worlds for balanced, healthy growth. What’s Organic-Mineral Nutrition? • Organic Benefits: Enriches microbial health and enhances soil vitality, building a strong biological base. • Mineral Benefits: Offers immediate, direct nutrient uptake for steady, balanced growth. • Why It’s Awesome: Plants get the best of both worlds, growing stronger, healthier, and more resilient.

So this beautiful OG kush has been finally Transplanted into her definitive 25L pot for this season, I've prepared the pot with the complete line of biotabs, I've added 25G of startrex for every 5L of soil, then I sprinkled a couple of grams of mycotrex on tje planting hole and after the Transplant was successfully completed I added 5 biotabs slow release fertilizer (one for every 5L of soil) and then just watered the plant immediately with 1g per liter of orgatrex and 1g per liter of bactrex, let's see how this beautiful OG kush pheno #1 develops!! Can't wait!

The Cookies ladies have been growing along side the Betty’s, doing their thing ❤️ The 2x4 is coming along, not quite as big and plump as my big tent, but producing some nice nugs nonetheless. The frost is starting! These girls were not as early producers, but seem to be responding well to the wind and light stress! The second trellis was definitely needed, even though they are not quite as tall as their grow mates. They have been keeping to the same schedule of needing to be watered every 72 hours. I will be switching from cal/Mag to Mag/Sulphur supplements later this week. I ❤️ how readily available these Advanced Nutrients are. 😎 The nutrient burn on some of the tips has not spread or gotten worse. The feed range seems to be the 700-750 range. Still keeping to the feed, water, feed schedule, with the 2nd feed being a much lighter dose of nutrients. I’ve increased the light intensity of the SF 4000 to 90% and will probably be stopping there. The temps have been getting as high as 81 degrees, and low as 73 at night. I’ve decreased the humidity to fluctuate around 50% , giving a reasonable VPD for most of the time, thanks to the automation of the in-line exhaust fan. Still have 4-5 weeks for these babies, I’m hoping they continue to plump up, they are showing some great promise. Happy Gardening 🤗❤️👊🇨🇦

Twenty20 Ateam R&D Update! Wow this week went so great, Germination was 100%successful!! We went with the usual paper towel method an they all popped up in the soil on Saturday the 28th! Let’s grow lil babies let’s grow!!

This was the first week with no nutes, just straight out of the tap water. I also upped the watering schedule to 3 times per day for 1 min each. I am thinking after watching this weeks timelapse that I will run the pump for 2 means on the parts of the schedule that the lights are on and see if that helps any. I also noticed that 1 of my plants, the one with the bigger buds and more crystals seems to be having its leaves turning yellow which I have tried to show in the last picture above. I believe it is because I have stopped feeding any nutrients and so now it is sucking what it can from the leaves. The other plants, especially my featured one do not seem to be doing this as of yet. I was hoping my closeup star of this diary, which happens to also be the tallest stem of the girls would also show the most growth, but as such, not much can seen to be happening. 1 more week to go before I cut and hang them to harvest and I will let you know how things turned out weight wise.

21 september What a week...nothing but rain. MAROC got chopped, she suffered from mould the worst. Grapefruit does a better job in this terrible weather. Few spot with mould were detected and those branches were removed. Every time keeping alcohol at hand to clean immediatly. Carefull not to spread the stuff. Curled/ twisted leaves, black spot are the first indications of rot. I have taken rotting flowers and leaves out and buried them. 2 weeks with little sleep and carefully checking every bud twice on each visit. Now we have 3 sunny days. She will get chopped before the next rain. Hopefully the sun to come is enough for her too bulk up a bit. I would love those calyxes to be fat and swollen. I have given up on reaching amber trichs. Weather wont allow it.

As I said, they went into auto flower. These girls are small but still going strong. Feeding foxfarm schedule Did have to repeat a few weeks due to the stress they went through.
