I used organic mix(Plant-tone) in potting soil, some 4-4-4, big bloom by fox farms, maxicrop seaweed, and the first grow had some 15-30-15 non organics. I still use some 15-30-15 at 1/4 if I see any problems with the organics, but usually just adding the organic mix works if they are light on any nutes.
Oh, the soil has pete, perlite, worm castings and no nute potting soil with the organic nutes. I forgot to add lime to this soil, and I am having to raise my pH manually from the pete breakdown.
