Im also using kindsoil, with coco loco ontop, tap water left out for about 2 days (my ph is 6.6 outta the tap) and my girls are growing beautifully. Ive met with Phil (owner of KindSoil) a couple of times, hes a super nice guy who really seems to know his shit. Dont hesitate to get a hold of him...
Ive been using Kindsoil with Coco Loco and I love it! Just add water, doesnt get any easier.
Kind Soil Never use nutrients again! STOP TRYING AND START GROWIN
the 3.5 gallon pots are fine, I wouldnt transfer them. the leaves at the bottom, cut em off. If they touch the dirt, they're more than likely gonna die anyways. Im unsure of your soils and nutrients so not sure what to tell you there. But maybe look into kindsoil. Its a super soil that I use to...
