I never foliage feed my peppers. I have plants 1-4 years of age with tree-like bark on their trunks. The largest jalapeño has a 3" trunk and is 5.5' tall!
I root feed organic fertilizers, iron supplement ( if a little yellow) and manures. The leaves get slightly chloriotic in colder weather, probably because my pH is so high.
These peppers are in awful soil but have had about 5 years worth of soil amendments.
Never till this garden because of it's location and the better soil isn't very deep. Underneath is red clay.
I do give fish emulsion and kelp to smaller or stressed plants.
I never have pests on the peppers except the occasional tomato worm. Sometimes I've seen a few whiteflies but never enough to cause problems.
