I have switched from "store bought" nutes like FoxFarm (which kick ass, by the way) to a more organic approach that can be purchased locally. Long Story!
My goal is to find the right (moderately strong and balanced) potting mix to transplant into after the first month. Then suppliment with "high-N" during veg and "high-P" during flower. Nothing very fancy here, just basic "KISS" (Keep It Simple Stupid!).
I am pretty new to doing organics "from scratch" , but learning is half the fun, right?
