I have a healthy ficus plant that has for years shown a curl on some leaves. The curl can be very slight or it can progress to destruction of the leaf tissue, giving the impression that it has been eaten. The majority of leaves are fine, but this problem has not gone away even with removal of all affected leaves. Though it looks like it might be insect damage, I can find no insects. The problem always occurs on the edge of the leaf.
