OK, so I thought I had aphids but now I am not sure. On my radish there are tiny black specks that jump off when I touch the leaves. They are so tiny that they don't even look like bugs. They are on my radish, lettuce and even all of the weeds I have. I will try to get a picture but they are so tiny they look like miniature onion seeds.
I knock them off and then they are back the next day.
