Maybe some nute burn also?
They’ve got plenty of life left in them and it’s weeks too early to harvest. I would simply back off the nutes, remove dead leaves, and keep them going for a while longer,Went south fast, but there were a couple of 118° days where we had power outages and also a couple of times when my drip system totally failed. Was going so well. I think some people chop at 8-9 weeks anyway but I'm waiting for amber trichomes.
