The leaves are fine. There is some damage from the aphids but overall they recovered well. It was just during the time when the aphids were the worst that I started noticing the spots. And they were worse on peppers that had more honey dew secretions from the aphids. I thought at first it was sooty mold because that is common with aphid damage. But it seems different than that. I have only about 40 peppers and about half have the black spots. They don't penetrate the pepper, just on the skin. I hope you are right Sandy about it being cosmetic damage. I can't really find any info online about it.
