Yea I've realized that now. My problem is keeping up with it. I've been giving her a weak watering of soybean aminos. It has a npk of 15-0-0. I cut the ratio down to 3.5-0-0. Think I might raise it to 7-0-0. I just wanted to see if the weaker dose would work.

I've also been top dressing with 1/4 cup craft blend and 3 cups ewc. I just raised the craft blend to a 1/2 cup last night.
Top water over your food daily,should help speed it up.

Blood meal and guano make me nervous. Lol
Ha, well my Gaia 444 has blood meal in it just needs a little more me thinks.I try to keep it simple and not buy too much stuff.Insect frass is another option or alfalfa meal.I bought a 20kg bag of alfalfa pellets I soak them to puff them up then dry them out.Grind them up and add to my soil.Was cheap $15 for what looks like a lifetime supply.

I have a cob fixture, qb fixtures, and strip fixtures. The strips run very cool. Plants can almost touch them without any burn or stress that I've noticed the qbs are a lil better but the cobs will burn the shit out of them under 12" with my fixture. :wall:
