I give the a dilute dose ( MAYBE 1/4 STRENGTH) when I move them from the germination tray to a growing tray-then maybe another application of 1/2 strength in a few weeks. When I pot them up for outside I again give them some 1/2 strength and then 1/2 strenghth maybe twice during the season. They don't need a lot of fertilizer.

I'm with Maine John. I grow in hydro and use 20-30% of recommended concentration with success.

Chiles are not very genetically engineered and can't use a lot of fertilizer.
