Is 20-20-20 fertilizer too strong for green bell peppers? I am having trouble with very thin paper like skins [no meat].
Fertilizer for Green Bell Peppers

You are too nice to them is why they have thin skin. Plants develop thicker skin to help protect them from the elements. I would guess that where your plants are growing is sheltered from winds and harsh sun. While I have not tried this personally, I am guessing that since reducing harsh elements on peppers makes their skin thinner, increasing it will thicken them. Try giving the plants a gentle shake every so often to trick them into thinking they are in a windier environment than they actually are.
