The several tests I ran and the small pots definitely hurt the yield because of the roots being bound up in the bottom of the cheap .8 gallon pots. Also recycling my amended promix from grow to grow is never going to happen again! This caused me caustic soil issues and ph issues as well. My next grow will be starting in two days and all the autos will be in 3.4 & 2 gallon airpots. Also I am moving from the general organics bio line to the sensi grow & bloom a&b ph perfect line, b-52, bud candy, big bud, and overdrive. So hopefully no more ph issues but I am also going to go with promix with pearlite, dolomite, and greensand instead of all the other slow release organics I was amending my promix with. All in all it was a lot of work keeping up with these issues but I love growing too much and the meds I provide are second to none!
