I use yellow sun for light source, I thought it's dried enough underneath. Do hot pepper need warm soil on below it?

They need warm soil and air temperatures. Daytime air temperatures need to be 65° to 80°F and night should be between 60° and 70°. If not, put a heat mat underneath and a lamp at least 12 inches from plants to supplement warmth.

Over watering?

is there something wrong with my sprout? it's 2 months old, lately some leaves has falling and some get yellow. I use organic fertilizer, made it from fish meal, avocado etc. Do I still need give it NPK fertilizer?
Maybe you can elaborate on that part a bit. If your 'fertilizer' contains any carbohydrates at all (and even if it doesn't) it can take many months to decompose and start providing nutrients, in the meantime increasing the COD of the soil 100s of times and harming the plant. I'd use a real fertilizer on a few plants and see if it helps or hurts. And maybe transplant a few plants in a normal fresh soil without fish or avocados to see if that helps.
Seems to be popular opinion on this sub to not fertilize this early... tho after I get my first set if true leaves I use some SUPERthrive (0.5-0-0) and it works fairly well. Only need a couple drops per gallon and plants love it. Also a tip I tried this year was to repot some of my "leggy" seedlings to where I can bring soil level to right below the cotyledon's. Just done this a few days ago and hit them with some SUPERTHRIVE and already seen improvement... just my personal experience.. I am still learning myself and no expert by any means.
