the Espoma organic line is carried by home depot. let your soil dry out some between watering and feeding. maybe cut a hole in the side of each pot so you can check dampness near the bottom of each plant container. let the top soil dry out, you will soon be able to tell later on as they get bigger by the weight of each pot before watering and a few days later ..... you want fresh oxygen entering topsoil then getting pulled into dry soil near the middle as you water .....

you can start off w/ ( organic start - starter plant food ) then use some Garden-Tone / Tomato-Tone combo ( 50 / 50 ) once they are bigger. just follow the directions on the back, but you will not need that much per pot. they will stay nice and green during grow.
if you want, pick up some bat guano online also if you can. ( sunleaves.com ) - ( Mexican 10~1~1 High Nitrogen ) for veg, ( Jamaican 0~10~0 High Phosphorus ) for flowering ........ but both are a slow release so only apply a few times during each cycle, go light with each.
and try keeping them in a little shade from 10.a.m - 1 pm , not hidden totally from sun but indirect light under tree branch ...... so they catch a break during high point of the day but still receive the early sun and afternoon sun. so they are not pounded 12 hrs per day .....
