hey there LockDownGrow, the short answer is "yes", but the long answer is "you dont want to". That's because what you're always trying to do is to have three things you're feeding : micronutrients like calmag, NPK like veg feed, and chelating agents like growzyne, organic rooter and organic bloom booster . You really only need one of the three at any given time. Growzyne is enzymes, rooter is kelp extract, bloom booster is humic acid. during early veg you're using the kelp extract , then start using growzyne and finally bloom booster. or just use either zyne or booster . i use humic acid like the bloom booster because it works the best out of the three. You only need one and it can even cause problems using more of them, not because they fight with the chemical feed but actually they might mess around with the pH and the nutrition. Does that make sense? Hope this helps ! π
