Last week of vegetation. Humidity has been a problem, it raises to 99%, the tent walls are condensing water. I'm thinking the micronutrients deficiency in the top right plant, that is showing in all plants now, may be because a potassium excess that's locking out them. It has other symptoms like thin blades and some brown patches in lower leaves. Bio-Grow is 4-3-6 so it makes sense. Last watering was without Bio-Grow. I'm being doing LST and some super cropping too to keep they growing to the sides. Also removing some leaves to clear the bottom and ones that cover too much lower shoots.
