I've noticed that a small number of the leaves on my pepper plants are showing several tiny holes through their surface. These are focused towards the stem of the leaf, and not so much towards the tips, and it seems to be effecting the top-most leaves, with only one or two leaves on each plant showing this issue.
Note that these leaves are not the ones I was seeing insects on the other day, in fact the plant that had the bugs on is the least effected, so I've a feeling these incidents are unrelated.
Is this a sign of a problem that I need to address?
