Well, by the end of the last grow, the stem of the plant was about as thick as the small rockwool cube, so I don't think its holding enough water to make a difference. Its likely that its completely consumed by roots.

The edges are crispy and the new small leaves around the buds have yellow, crispy, turned down tips. The guide I read said a little P deficiency in flower is normal, but if P is what it is, I think I have more than a little. What should I do? PPM is 1150, pH is 5.6, double checked with liquid pH kit. They are starting Week 4 tomorrow. The last pic is what I would say is the worst looking one. Rating: 5
