I forgot to mention one more suppelment I use, concentrated humus. Its some stuff I bought off of ebay, it was a concentrated powder, that was mixed to one gallon of water. I used rain water to make it. Of this mix I only use 1 ounce to one gallon of nutrient mix. I dont use it for every nutrient mix though, maybe once every 4 gallons. When I finish this stuff, I'll be switching to liquid karma.
