the burn along the leaf margins is old. As it dosn't go away it's been there for a month or so. I think i mentioned that i had them on hard nutes and then noticed burning. (thats it) I have already given them a bunch of nutes, now onto flowering nutes. and it really slowed the disorder.

See i dont think it could be burn because i nuted my plant say a week ago. It was chilling out, then one day i wake up BANG! this is what it looks like.
that owuld be like delayed nute burn.
