Hey! if you do Soil Indoors you can always follow Reikos Ammended Coot Mix
I find soiless easier than that tho. I do peat with vermiculite and perlite and feed Peters Peat Lite Special at 1.3 EC (you can also use Jacks, its basically the same thing) from start to finish (with some added phosphorous in flower). Its the “Bugbee” method from USU. you can find the video here.
Also, ive made some notes on both organic and inorganic growing here if it helps you at all.
