Foliage disease, what is it?

Thanks guys. I have had aphids and the occasional horn worm but the flea beetles are a first. I don't spray for insects until I have to and then it's pyrethrin or neem oil. I pruned most of the damaged leaves which turns out were the lower older stems anyway. I gave them a good spray with peroxide and then sprayed them with pyrethrin and rotenone. I prefer pyrethrin alone but all that was available was pyrethrin with rotenone so they got a good spray of it. So far no new damage.
