I have no other nutes to compare this product to, however, I'm really happy with Humboldts in the fact that I never have to adjust my pH. The combined addition of cal-mag and Humboldt's to my 7.1pH tap water always brings it to a perfect stabilized 6.1-6.2pH level. I've also used this on other plants (vegetables) and had great results. If you're a beginner such as myself and want to enjoy a worry free grow with little to no nutrient hassles, I'd highly recommend Humboldts. 😎👍
