Rabblecron I think u need to do some reading on growing weed inddors cuz your doing several things wrong. I dont understand why u would use heat lamps as supplemental lighting..

You never want the soil to be totally dry between waterings, just when u notice the top layer of soil drying out a little, is it time to water.And are the liquid wormcastings the only fert uve been using because yellowing leaves can be a sign of nitrogen deficciency?

I use worm castings(N) in conjunction with bat(N), and peruvian sea bird guano(P), kelp(K), plus some synthetic Nutes too.
