Hello. I have this leaf curling I'm finding on many plants and mainly on newer growth. I've yet to find a bug in or around the problem areas. They tend to like my passion flower leaves the best but will do it to most anything. It looks like a bug pinched off a vein in the leaf when it is first growing then just curls up around the pinch. Here are a few shots of what the damage looks like.
I would really appreciate help in finding out what is doing this. I'm usually pretty good with this sort of thing but not on this one.
Thanks, Jeff
