Do you think you could give us any less information to work with?

What insects? How bad is the damage? Are the pods okay? Got pics?

Dennis

I don't see any insect damage at all. The one picture suggests black spot which is a fungal disease that commonly affects roses. The others look more like fertilizer burns. Do you fertilize with a shower-head type watering can?

Dennis

Yea, that's not from insects..

i dont fertilizer at all

if i dont fertilize what is it from and bottom leaves of peppers are turning yellow . why do the holes look like insects on peppers and cukes/?

Don't know. I will say that the newer leaves look fine and the plants look healthy and are fruiting like crazy. Older leaves often accumulate damage from God know where, and as the plant grows are discarded as they get shaded out.

I don't think you have anything to worry about.
