Tell me what you think.

I've looked through the site of possible problems but not sure. The leaves are also turning yellow on some of the lower fan leaves.

Is this what I'm thinking it is? If that's a hair, I'd like to correct the problem with the leaves if possible.



These pictures are from the same plant.

How old is it?? Might be a pistil. might be new growth too. and that looks like nute burn.

3 and a half months old maybe. I don't think it's nute burn, I haven't been giving them any.

heat stress? those possibly could be hairs. how tall are they? flip ur lights to 12/12 for flower and see.

Sounds and looks more like a deficiency to me..Maybe cal or mag..Check this thread https://www.rollitup.org/marijuana-plant-problems/118601-guide-plant-deficiencies.html... Looks like it is starting from the edge of the leaf so find which deficiency(s) start from the edge of the leaf and looks like yours

It's possible that it could be heat stress, it's been pretty hot here for three weeks. 3 and a half to 4 feet. These are grown outside skunkmeister.

That could be it, but I agree with L2G it definitely could be a deficiency.
