It's a Calcium/ Magnesium deficiency, for some reason plants under LED lights crave more Cal-Mag.

What is causing PK deficiency signs on mid leaves? Too little Calcium causing lockout??Hey everyone, in mid and late flowering with my autos, all experiencing similar problems and I’m inclined to believe it could be due to a lack of Calcium? Could a Ca deficient plant cause these symptoms which resemble a PK deficiency?? I’m 100% adding enough bloomWeek 11
