Hi Guys, I put my plants under the HPS (400w) like 5 days ago and now they look like the pics underneath. The leaves are looking like they dry out or something, they turn yellow with little brown spots on them and then they fall off.
I don't think I water too much but I think it might be caused by over ferting, they're a month and a half old but still very small cause I couldn't remove them from my crappy cabinet earlyer.
I use distilled water with a little added Ammoniumnitrate and potassiumnitrate (maybe these are too strong ferts)
Any Idees of what I could do? Does this even look like nute burn or is it something else?
Any help is very much appreciated
