wow thanks for all the quick replies.

yeh i'm a little reluctant to feed because i burned one of my plants last grow by accident. the soil still seems a little damp also, and i also overwatered my last plant a couple times.

where would be the best place to get superthrive? a nursery? i'll have to look one up in my area.

when is the best time of day to feed? at the beginning, middle, or end of the light cycle?
