What is this? I added UV light to my grow tent and this plant reacted in this way. None of the other 3 plants had any issues including the sister plant. Tops of the colas with this issue are dried and crispy, undersides seem pretty healthy.
I think UV is a good idea to keep mold away. Still with sticky buds, mold would come any way. And when mold is killed, flowers died without the fluffy wet stuff.
I would stop feeding. And keep searching for this sort of stuff every day.
If too many keep coming up, I would begin with early harvest. Less is better than none.
So I ended up cutting those burnt tops off as I was afraid of mold starting to develop and of course it had. Will see how it goes, have another 10 days before the planned harvest but will see how it goes.
