Week 2 - Vegetation | Black Diamond Auto Pheno B
Hello everyone, and welcome back to another update from the 12/12 From Seed adventure.
Today we’re checking in on Black Diamond Auto Pheno B as she continues her journey through the early vegetative stage.
For anyone joining the diary for the first time, this project follows a 12/12 From Seed cultivation approach, documenting each phenotype individually from germination through harvest. One of the most enjoyable parts of this process is watching how different plants express themselves, even when growing side by side under the exact same environmental conditions.
Black Diamond Auto Pheno B has certainly started developing a personality of her own.
Throughout Week 2, growth remained strong and consistent, with the plant finishing the week around the sixth to seventh node while continuing to build a compact and balanced structure. The canopy is developing beautifully, and when viewed from above, the symmetry is immediately noticeable. Every new growth point is stacking neatly, creating the kind of shape that growers love seeing during the early stages of development.
One of the most interesting observations this week comes from a small quirk found in one of the earlier leaves. Rather than forming completely separate leaflets, two fingers appear partially fused together, creating a unique shape that immediately catches the eye. Fortunately, this has remained purely cosmetic. New growth emerging from the center of the plant is developing normally, showing healthy leaf formation and excellent vigor.
These small genetic curiosities are one of the reasons documenting phenotypes individually is so rewarding. While Pheno A introduced us to a beautiful camouflage-like leaf pattern, Pheno B decided to express herself through a slightly unusual leaflet structure. Neither trait has affected health or performance, but both contribute to the unique story of each individual plant.
Beyond that little piece of personality, everything else continues moving in the right direction.
The transplant completed previously appears to have been accepted without issue. Root development is clearly supporting vigorous above-ground growth, and the plant continues expanding steadily with each passing day. Stem development is strong, leaf size is increasing, and the center growth is becoming increasingly active as the week progresses.
Coloration remains excellent throughout the canopy. The foliage displays a healthy, vibrant green tone from top to bottom, while leaf posture remains upright and confident throughout the photoperiod. The plant shows no signs of stress and continues responding positively to the stable environment provided inside the tent.
Nutritionally, the feeding program remains simple and focused on establishing a strong foundation for future growth. Plagron Terra Grow provides the primary vegetative nutrition, while Power Roots supports continued root development following transplant. Pure Zym assists in maintaining a healthy root zone by helping break down organic matter within the substrate, and Sugar Royal continues as part of the overall cultivation strategy for supporting healthy plant metabolism throughout the cycle.
Sometimes the most successful weeks are the quiet ones. No major interventions, no major corrections—just healthy growth, stable conditions, and the plant doing exactly what nature designed it to do.
Overall, Week 2 has been another excellent week for Black Diamond Auto Pheno B. The structure is beautiful, the growth rate remains impressive, and the plant continues proving that a little early quirkiness can coexist perfectly with outstanding health and vigor.
Thank you to everyone following along, supporting the diary, sharing advice, and contributing to the incredible growing community that makes projects like these so enjoyable to document.
A special thank you as always to Zamnesia for the genetics, Plagron for the nutrition, and to all growers around the world who continue sharing their knowledge, successes, and lessons learned.
Until next week, growers love and happy growing everyone. 🌱💚
