💎 Black Diamond Auto by Zamnesia – Pheno B | Week 3 Flower The Quiet Sister Is Starting to Shine Not every plant needs to be the biggest in the room to deserve attention. Sometimes the more interesting story belongs to the one quietly developing in the background, steadily building her structure while her sister is busy taking every photon she can find. That is exactly where Black Diamond Auto Pheno B finds herself this week. Her sister, Pheno A, continues to be the more explosive phenotype of the two, pushing larger and more dominant flower clusters and naturally demanding attention whenever I open the tent. Pheno B? Well... She's a little more shy. 😄 But I'm pretty sure she's still walking around the room looking for those extra photons. Unfortunately for her, Pheno A seems to have already collected most of them. And yet, when I stop and actually look at Pheno B, there is a lot to admire. She may not be producing the same oversized colas as her sister, but she is developing into a beautiful, balanced plant with exceptionally healthy foliage, excellent flower distribution, and a very elegant structure. This is exactly why I love documenting individual phenotypes. Same genetics. Same environment. Same nutrition. Same lighting. Same irrigation. Same training philosophy. Two completely different personalities. And Pheno B is beginning to show us hers. 🌱 12/12 From Seed Like every plant in this project, Pheno B has been grown using my favourite technique: 12/12 From Seed. From the moment she emerged from the soil, she has lived under a flowering light schedule without an extended vegetative period. No topping. No high-stress training. No aggressive manipulation. Just gentle Low Stress Training, leaf tucking, observation, and allowing the genetics to decide how the plant wants to develop. And this phenotype is making a very convincing argument for that approach. Her architecture has remained upright and elegant, with flower sites developing progressively along the branches rather than forming one massive dominant structure. She isn't trying to become the biggest girl in the room. She's simply becoming her own girl. And I really like that. 🌿 Environment Another week of stability inside the flowering room gives these plants exactly what they need: consistency. 🌡️ 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 💦 Watering: 1.3 L per plant / 24h ? Pot Size: 15 L 📏 Plant Height: approximately 160 cm The root zone remains stable at 21°C, while the nutrient solution is also maintained around 21°C. This kind of environmental consistency is something I value enormously. The plants don't need to spend their energy adapting to constant changes. They can simply grow. And that's exactly what Pheno B is doing. 🌿 Training & Canopy Management The training philosophy remains unchanged. Gentle LST continues to guide the branches outward, while leaf tucking is used whenever necessary to open developing flower sites. There is still no defoliation. The fan leaves remain healthy, green, and highly active, so I see no reason to remove them simply for the sake of creating a cleaner-looking plant. Those leaves are working. They're capturing light. They're producing energy. And Pheno B still has plenty of flowering ahead of her. So for now, I prefer to let her keep every healthy solar panel she has. Sometimes the best training decision is knowing when not to interfere. 🌾 Feeding Program The flowering nutrition program continues supporting the transition from stretch into increasingly active flower production. Current feeding includes: • Plagron Terra Bloom – 2.2 ml/L • Plagron Power Buds – 1 ml/L • Plagron Green Sensation – 1 ml/L • Plagron Sugar Royal – 1 ml/L • Plagron pH Plus – 0.03 ml/L • Plagron Lemon Kick – 0.03 ml/L Current solution strength is around 2 mS/cm, with the irrigation maintained at approximately 1.3 litres per plant per 24 hours. And visually? She's loving it. The foliage remains a beautiful, deep green without showing obvious signs of excess or deficiency. No dramatic corrections are necessary. No reason to chase numbers simply because we can. The plant is telling us that she's comfortable. So once again, the best decision is simply to stay the course. 💎 Phenotype Spotlight – The Quiet Sister This is where Pheno B really deserves her moment. At approximately 160 cm, she has developed into a tall, elegant plant with a very different expression from her sister. The colas may not be quite as large or aggressive as Pheno A's, but there is something incredibly attractive about the way Pheno B is building her flowers. The plant is covered in developing sites. The branches remain nicely spaced. The flowers are stacking progressively along the internodes. And the entire plant has that beautiful, healthy green appearance that makes you stop and look twice. Her slender leaf fingers continue to stand out as one of her most interesting characteristics. For a heavily indica-dominant Black Diamond Auto, this particular phenotype continues expressing a surprisingly elegant, narrow-leaf appearance. It's another reminder that genetics are never quite as simple as a percentage written on a seed description. You can grow two plants from the same genetic line, place them in the exact same environment, and still watch them tell completely different stories. Pheno A is the loud sister. Pheno B is the quiet one. But quiet doesn't mean uninteresting. Far from it. 🌸 Flower Development This is probably the most exciting part of this week's update. The flowers are becoming much more defined now. The early framework of individual pistil clusters is beginning to transform into recognizable buds, and the calyxes are progressively stacking along the flowering branches. The pistils are still predominantly fresh and white, although a few are already beginning to change. The flowers are also carrying an increasingly visible layer of resin, especially around the sugar leaves and developing calyxes. It's still far too early to make any serious predictions about the final level of frost or aroma. But the first signs are definitely there. And sometimes that's all you need. A little sparkle. A little promise. A hint of what might be waiting several weeks from now. 💡 The Photon Hunt Continues One of the funniest differences between these two sisters is how they seem to approach the light. Pheno A? She simply takes it. Pheno B? She looks like she's still searching for more. 😂 With her more open and elongated structure, she seems almost determined to explore every available pocket of light inside the room. But there is a problem. Her sister is already standing there. Taking it all. Pheno A continues producing those larger, more dominant colas, while Pheno B is developing a greater number of beautifully distributed flowering sites. And honestly, I don't think that's a bad thing at all. Different architecture. Different flower distribution. Different potential. That's exactly what makes a phenotype hunt interesting. 🌿 Welcoming Lumiflora The introduction of the Lumiflora under-canopy lighting system is also becoming increasingly interesting as flowering progresses. The goal is simple: Complement the overhead lighting by bringing additional usable light into areas of the canopy that naturally receive less intensity. Pheno B's more open structure makes her particularly interesting to watch under this setup. Rather than trying to predict exactly what the additional light will accomplish, I'm choosing the approach I always prefer: Document it. Observe it. Compare it. Then let the harvest tell us the truth. 🔭 Looking Ahead Over the coming week, I expect the transition toward heavier flower production to become increasingly obvious. The remaining stretch should continue slowing down, while the developing flowers begin putting more emphasis on calyx expansion and stacking. Pheno B may never produce the same massive cola structure as her sister. And that's perfectly fine. Because she's building something different. She's becoming a tall, elegant plant covered in beautifully distributed flowers, with healthy dark-green foliage and an increasingly visible resin presence. Maybe Pheno A is the sister everyone notices first. But Pheno B? She's the one who makes you stop when you finally take the time to look. And I think she's going to surprise us. 💚 Final Thoughts There is something incredibly rewarding about watching two sisters grow side by side. One is more explosive. One is more reserved. One seems determined to conquer the entire tent. The other appears to be quietly wandering around asking where all the photons went. 😂💎 But both are expressing the same genetics in completely different ways. And that's the beauty of phenotype hunting. Pheno B doesn't need to beat her sister. She simply needs to become the best version of herself. Right now, she's on a beautiful path to doing exactly that. Her foliage is lush. Her structure is elegant. Her flowers are developing beautifully. Her resin production is beginning to announce itself. And she's slowly transforming from the quieter sister into a plant that deserves her own spotlight. So this week, the spotlight belongs to her. Black Diamond Auto Pheno B. The quiet sister. The photon hunter. And maybe... just maybe... the one hiding a beautiful surprise underneath all that green. A huge thank you once again to Zamnesia for providing these Black Diamond Auto genetics, to Plagron for supporting this journey with their nutrient line, and to Lumiflora for joining the project with their under-canopy lighting system. And, as always, thank you to the amazing GrowDiaries community for following along, sharing your knowledge, and enjoying this journey with me. Two sisters. One genetic line. Two completely different stories. And we're still only getting started. Until next week... Growers love and Happy Growing! 🌱💚

its been a hot dry week but the girls have fared it well. mound design and soil content have helped keep moisture in the root ball of the plants. Hopefully we get some rain this week otherwise im going to be spending a day just watering them. fingers crossed for rain. We need a rain dance here.

The beast plant is yellowing a bit. i think its either because it got to big or its getting heat stress. a little curious, but nothing to do but truck on and see how things go. all the other plants seem to be very happy and doing things the Mephisto way! Will update as week continues! ☺️☺️☺️Don't judge my video to much. its hard to make these things!☺️☺️☺️ >>>>>https://viparspectra.eu/discount/MrHighitmes<<<<<

So this little lady has also shot up looking very plump and reaching for the sky , she is how ever slightly smaller than her other tester seeds sister the FBT7 But are looking full of vegour , thursty for there first nutrients next week once ive worked out the correct doses

More pics and videos coming soon

Just put 1 seed on soil and put water

I’m overjoyed with the phenos this strain is producing, strong vibrant purples with some serious flavour profiles! Scent Profiles we have: Candy Lemon Sherbet 🍬🍋 Sweet & Piney Diesel 🍭🌲⛽️ Sweet & Tangy Tropical Punch 🏝️🥊 Alongside this, these beauties are the frostiest and the most insanely dense koala looking nugs I’ve ever produced!

Helloing👋🏻 friends and visitors. Flip them Clones last Tuesday 12/12. Did some defoliation. Feeding: Tue31st:2L each w/nutrients ph'd 6.25 Fri 3rd:2L each water only ph'd 6.5 Mon 6th:2L each w/nutrients ph'd 6.22 ----------------------------------- The game is on!! Let's see what i can get, out of them Black Candyland "indoor" Clones! 🤞🏻😂 This is it for this weekly update. Thanks for stopping by! Likes and comments are appreciated. Keep on growin! Keep on tokin!!! 😙💨💨💨💨💨

Checkout my Instagram @smallbudz to see the Small budget grow setup for indoor use, low watt, low heat, low noise, step by step. 07/12/2019 - Fed her 2l of 6.5PH water with 0,5ml of each Grow, Bloom, Max and Alga-mic, and 1ml of each Heaven and Vera,noticed about 10% run off, also added a green filter to the camera lens. Adjusted the light distance to 55cm again it was toooo close about 32cm. 10/12/2019 - Decided to go back and check the basics, removed led strip to give a proper 'night' time, changing light cycle to 20/4h no more 'exotic' 22/2h, re-checked the light distance every 2 to 3 days to ensure 60-45cm and I can tell all ready she is loving it. Also added home made Co2 made with 1 tsp of yeast, 3/4 tsp of sugar 700ml of warm water in a 1l bottle with a tiny pin hole on the cap. 11/12/2019 - Fed her 1.5l of 6.5PH water with 0,5ml of each Grow, Bloom, Max and Alga-mic, and 1ml of each Heaven and Vera,noticed about 10% run off. 12/12/2019 - 8 weeks have passed and no flowers I guess I'm flipping to 1212h to see if she reacts.

Had a small issue this week where temp dropped a bit, I was on vacation for a few days and a window got left open to the room the tent is in. The room got down to 62f with the lights on. lights off temp wasn't much cooler. I noticed some canoeing on leaves near the center of the room, I am hoping this was just caused by the temperature stress that happened by the sudden drop. I fixed the temp and issue and it should be back to normal. Trichome's look great under microscope. Getting tightly packed and very cloudy, very little amber color at this point. Cheese #1 Has swelled up quite a bit over the last 5 days, The buds on it are noticeably larger than the ones on Cheese #2 I have moved the led light to cast more on cheese #2 in hopes to get the buds on it to catch up to #1 Still dealing with small calcium deficiencies, I will do a light flush this week of 1/2 strength nutrients and Cal at 6.5 Mid Weekupdate: Flushed plants with 1/3rd nutrient dose and full strength cal mag. Adjusted ph. to 6.5 to allow for better uptake of calcium. The calcium issue isnt bad just some small spotting but I am trying to get ahead of it as there is supposed to be 4 weeks left on the strain. The buds have started to tighten and get more dense. Hairs are about 40% red, some are receding into the bud. Smells like citrus.

ESTAS PLANTAS LES QUITE 2 NUDOS DE GOLPE Y SE PARALIZARON, SE VE QUE SE ESTRESARON Y SE QUEDARON PARADAS, YA ESTAN EN FLORACION VEREMOS EL RESULTADO FINAL QUE TAL

07/11/25 - Watering 1.5L each daily 😇 08/11/25 - Watered 1L plain Ph5.9

19.1.25: I have watered all plants with 300ml of dechlorinated water PH'd to 6.3, with 1/3 jar of black strap molasses with Ecothrive Biosys-1g. I am looking to increase the sugars for microbial life and plant processes. It'll also add some extra Calcium, Magnesium and trace elements. I also, watered all plants with Bloom nutrients. Using dechlorinated water PH'd to 6.3 with the following nutrients: (ml/l) ;- ♡ 2ml Cal-Mag ♡ 2ml Ecothrive Flourish ♡ 2ml Xpert Nutrients Bloom Booster ♡ 2ml Biobizz Bloom ♡ 2ml Biobizz Top Max ♡ 1g of Ecothrive Biosys I watered around 1-3 litres per plant. Depending on size and requirements. I'm still spilling water containing the nutrient solution. 🙄 I am using this to rub into the leaves. I think a nice foliar massage won't do any harm, make the most of the situation. The plants have become very hungry and thirsty. Increased the water by double. I ran out of my TNC cal-mag. I decided to order the Xpert Nutrients brand, as I like their products. It isn't organic as far as I can tell, but I don't think it matters too much to me, to be honest. I also want to top dress this week, so I bought some Green Leaf PK bud Booster dry amendment from Amazon, too. I'll mix it with canna coco, perlite, worm castings, and Ecothrive Life Cycle. 24.1.25: I went ahead and top dressed all the plants with 4.5 gallons of my supersoil custom mix. This consists of the following substrate and dry amendments: ♡ 60% Canna coco ♡ 20% Worm castings ♡ 15 % Perlite The remaining 5% consists of the following dry amendments;- ♡ 10g Ecothrive Biosys ♡ 1 Tsp RHS Mycorrhizal Fungi granules ♡ 3 Tsp Vitalink Bat guano ♡ 4 Tsp Diatomaceous earth ♡ 8 Tsp Ground Cinnamon ♡ 10g Green Leaf Bud Booster PK booster. ♡ 3 Tsp Ecothrive Life Cycle. •Worm castings for some all round nutrition. •Cinnamon for mildew and bug repellent. •Canna coco base substrate. •Perlite for adding oxygen to the root and soil system. •Green Leaf Bud Booster PK Booster for blooming. Building strong big buds. •Vitalink bat guano again for Bloom. •RHS Mycorrhizal Fungi granules, to boost beneficial microbes. •Ecothrive Life Cycle for lots of great benefits. •Diatomaceous earth for Silica. •Ecothrive Biosys, for an extra microbial boost. Thanks for checking out my diary 🍃 ✌️

Week 5 and all 6 Autos are kicking out white hairs Auto ultimate still the biggest out the lot tallest being just over 3ft tall the rest are around 2/2.5ft tall and still stretching

Second week of flowering and they are are already getting fatter and stacking nicely. Sorry for the poor pic and video quality.

So amazing strain

There isn't much more to say about this fantastic strain. Hardy, easy to clone, quick to flower and absolutely delicious in every respect. It resists well to high temperatures, "accidental" over fertilization, and recovers soon after a period of drought. Easy and fast.
