Thanks for the response
@drdawg! It's the older leaves. It might have been present when we bought it, but since we've had it, it has started happening on more and more leaves. Since we repotted the leaves are starting to droop as well. I've attached two pictures (sorry the light is bad). I'll start watering it more. Lots of blogs I read said repotting might have "freaked out" the roots. Is there a way to help it relax?
