I have four auto pounders on the go using biobizz nutes and bio bizz light mix soil. They've been getting 2ml of grow up until week 3 then 2ml of grow and bloom since then. The leaves r turning lighter green and the tips are yellowing but only on one plant out of the four. It's hard to burn on organics so I'm thinking cal/mag def or low nitrogen. Confused please help. All others r fine one on the bottom left is the problem u can see the tips r yellowing.
