Not sure wtf is causing this. Leaf tips on new growth is burning and looks like a Mg deficiency that I cannot solve
Seems like it’s the growth under the big fan leaves that are doing it the worst so it’s not light stress.
315w CMH about 24" above the plant
Dwc 1.2EC but 0.2EC is tap.
Looks like maybe zinc but I don’t know how. I’ve been using Jack’s 5-12-26 which has never left me with a zinc deficiency before
