Northern Lights Autoflower 1

A couple of weeks ago I suddenly had rust colored spots springing up all over the leaves, and thought it was rust fungus, but I had put some vegetable plants in the grow tent then noticed little bugs flying around and the bottom side of the leaves looked like something was eating at them. I have gotten rid of the bugs and source of them, and did a defoliation to remove the damaged leaves. We will see what happens next.
