The three part? Search for the Useless Formula. That one is a good place to start. I dropped the additives in the formula except for the kool bloom. I haven't used general hydros nute schedules in a long time. But if I was going to use theirs I would start by dropping the additives except kool bloom and cal mag as needed, and cut the base formula by 20%. See how your plants respond and go from there.
