I would guess it’s P deficiency. Had same symptoms in my grow. Also should check exact PH, maybe it is at the level where P is not absorbed.

@Myfriendis410 @dbrn32 @MidwestGuy so I went with everyone’s suggestion and got the QB 260 kit and i’m loving it so far. Here’s an update on the plant, some leaves are developing these tiny brown spots. Maybe someone can tell if its anything serious?

Would guess it’s calcium defieciency. Rusty spots and twisty ends of leaves. I’ve read, that if using LED lights you should add extra calmag. Had same problems, the increase in calmag made improvement.
