Had a friend look at them and he says its possibly Powdery Mildew....

Recommendations? I need them asap

Lookʻs like PM, I suggest Eagle 20EW. You have to order it online but itʻll wipe out the PM. Itʻs not Organic, but itʻs basically the TITS.

Yeah its p.m. Stay organic and get Einstein neem oil or if you can find it A product called Bhang. Its organic keeps down mites and p.m. Bhang also helps heal wounded or stressed ladies. It could of been on your clones from the start, transferred, spores through the intake. Damp,humid,and stagnate air is a breeding ground. It can be dealt with, but tough to kill if you indoors. Good luck.
