That is insect damage of some sort. In the second picture it shows spider webs which could be spider mites. I have never seen them do that type of damage though. To make sure I would spray with Neem Oil over the entire plant. If it is mites this should take care of them. But, to be on the safe side I would spray again with a spinosad based insecticide a day or two later.

Sawflies do that sort of damage too
