I use Botanicare as well... I don't use the Karma or the Cal-mag. I replaced the calmag with mollasas only in soil. I use the bloom and the grow.. Have been for 2 years. It's better than over fertilizing.. You can easily do that with other nutes. Lemon will make the mix acidic.. ph would work at 5.8,even lower. Not much though.
