Black Ultimate — Screen of Darkness

At this stage, my main mistake was that I did not raise the lamp enough above the plant. This caused the tops to turn white. But this is not a problem, in the future they will recover. I deliberately give a lot of light and a lot of phosphate fertilizers at this stage. The tops stretch out, becoming narrow, which is beneficial for me in a small box. You can see signs of light stress and nitrogen deficiency, but it's all part of the plan.
