This stinks. I'm using the exact same nutrients and soil you are. Good work. But make sure you don't start using the fox big bloom or tiger until they're almost ready or in bloom. I'm also growing in a small, 2 by 2 closet. 150 Watt HPS and supplemental flouros. P.S. I grew this strain from a seed I found in a bag from outdoor-grown CO buds; I've been cloning this strain for almost a year. And I'm not going to lie, people will kill for this bud when it's harvested. If you like the pot you're smoking and somehow manage to find a seed....plant that sucka.
