As far as a plumeria can have a bad hair day I guess.
I brought it outside to get some real sunlight and fresh air after being inside all winter under a grow light. The wind was something it wasn't used to anymore and one of the leaves seems to be permanently turned over like a lock of hair out of place.
I've since had to bring it back in due to a cold snap and the leaf still doesn't want to return to it's proper place. Fortunately there are new leaves coming in and it should be falling off in the next couple months.
