They look dry and the hairs that started out green have a little brown on them now... it's 2 1/2 mouths old 150 HPS bulb, does have fan that you can't see in pics.
Yes, next light cycle. The fan leaves are dark green except for the top tips that look lighter are in fact just a lighter green. From random bag of grass so that might be a factor?
Does the light look far enough away? It might be heat damage?
