I have no clue either, Hap. I had a similar thing like Brin said when my temps got so hot, and not all the branches were affected. But mine were just the tops

Your stems look green from here so I bet they will be fine. If the stems look hinky or the other leaves wilt, it could mean big trouble.

And I always blame and treat for mites if I have no clue. LOL. Though usually mites affect all of the plant, not just a few branches, at least at my house.

Heat stroke.
