Same thing happened to me with my mother, she was showing the same signs and i believe it could be nute burn as well as temp stress.

Problem got solved by flushing her and pruning all of the dead parts on the leaves. Took a while to recover, but I'm sure your girls will be fine.

O ya and nice grow...

I started with 8 hybrids (white widow, and pure power plant) and 1 indica (blue hash) and they've done extremely well but I'm noticing what looks like some sort of deficiency maybe... They are 85 days from seed and have been flowering for 33 days now. Now for their environment: homemade 3' x 4' area covered with panda film, Rating: 5
