I'm gonna try that then. I'm runnin 5 gallon pots and my mediums are so mixed even I don't know what's in there! I have OG (not sure which cut), LA Confi, Sour D, White Russian, and Purps runnin right now. I was going by the directions per GH (Grow and Micro) and supplement a B1, and some Cal Mag and then I give them plain ol water on the next watering. Everything looks great. I also have a Homer bucket bubbler out back with some Russian just to see the results outdoors. The roots are going crazy. I need to start a thread, I know. Thanks bud!
