Original Glue Pheno Hunt

Did some topping for 3 plants, 1 pheno is falling behind and seems to have trouble developing roots. Refreshed the reservoir with extra calcium and rhizotonic to see if it can catch up. If not I’ll throw it away. Roots look white and healthy for 3 of 4 plants. 1 of the 3 fast growers is showing some calcium deficiency. This also explaines why the small plant is falling behind. Since pheno 1 and 2 don’t show any signs of deficiency I’ll just stick to my normal feeding schedule and see if the situation worses or not.
