Hibiscus: Leaf Damage, 0 by BARHARBOR

Okay, I have 4 different varieties of Hibiscus: Donna Lynn, Petra, Headmaster and Chinese Lanterns. Both the Headmaster and the Chinese Lanterns have leaf damage at the leaf margins (the other two varieties have no such damage). I can see no leaf chewing or sucking insects. There are no stippled leaves or webbing, no nothing that points to a specific mite or insect that is chewing on them. I suspect that it might be some microscopic mite that's attacking the leaves before they come out.

Anyone have any experience orr input that might help me out?

Thanks!
