Thanks everyone for the advice. Discus might be on to something...I'm wondering if maybe the leaves were touching the window glass the other day. It has been really cold here for the past week. I didn't think anything of it because it's been so hot inside the house. I'll try cutting back the leaf and keeping an eye on it for now.
BikerDoc, I don't think I've been over feeding it because I've hardly given it any fertilizer at all since I got it. But it is packed pretty tight in sphag right now so it could be build-up. I was waiting for it to finish blooming before re-potting it. I think I'll do that ASAP.
Thanks again!
