I have a little bit of a mystery on my hands....ph and everything is perfect I know its nothing to do with nutrients I'm using and I cant find any bugs even with microscope. so why are the Black Russians I am growing doing this?
I may have sprayed nutes on them because the affected areas seems to be in a group but I have never seen this bad of results for getting nute spray on the leaf.
Thanks in advance for any help.
