Tropicals & Tender Perennials: Is this just from sun/heat?, 1 by KaperC

This bud is on a large epi strictum that was burned some time ago - hence the red foliage. It blooms just fine, though and has several healthy buds ready to pop in the next week or so. I'm just curious about this bud - I've had a lot of them. They turn orange-ish, then black, and fall off. Looks like someone took a torch to them.

We have been having much hotter weather this summer than usual - instead of a few days it's turned into months in the 90's-100, high humidity, winds, etc., so I'm wondering if this is caused by the weather or is there something to worry about?
