If the leaves are more than 50% destroyed I'd probably pull them; less and I'd probably cut off the dead parts of the leaf and try and leave the healthy part. I know sickly leaves invite mold, fungus, etc so I worry about it but I tend to lean towards the paranoia. The dead cola I'd chop and dump. I agree with UGU that the stress level is probably way up so I'd make sure it's on the rebound first.
Weedhound Reviewed by Weedhound on . SHOULD I CUT THESE LEAFS OFF? (PICS) The Ph got off on me with this plant. I think it suffered some heat stress, and a nute lockup. It has since turned around I think, Its been flowering for 6 to 7 weeks now. I have pollinated it to get some seeds. I can see lots of seeds and the sacs are starting to open. The fan leaf stems went completely purpal and the leaf tips started to curl down, as well the edges of the leafs curled up. I read this could be many problems. mainly a P and K lockout and maybe a Mg deficency. I fixed Rating: 5
