Low water would compound heat stress, but if as you say it is otherwise perfect, that isn't the problem, since you would also be seeing some droop.

I still think you should try getting your temps down to the 70s and give it a little time to recover. Another thing you can try is giving a silica supplement such as Silica Blast. That helps plants resist temperature extremes.
