check underside of leaves for spider mites.................

Looks like thrip marks perhaps. Also I can see overwatering I think??? Also Mg, which can't be absorbed in wet soil and ur using RO. Let them dry out and get the Neem oil ready.

I hate inscets that thrive on cannabis juices! Hey wait i thrive on cannabis juice's! lmao! Yeah hopefully you got some neem around to smash those buggers down.

i set a pyrthrium bomb off on 10-2-2012, and i popped a second bomb this morning. so hopfully the problem is taken care of. im gonna let them dry out a bit and see if they get any better.
