This nutrient powder causes my nutrient solution to become highly acidic. I'm not sure of the chemical processes which are causing that or if there is anything the manufacturer can do to have the mix be more basic when mixed into water, but wow... I have to use a ton of hydroponic PH raising solution to balance the mix to 5.5 to 6PH. We're talking bright deep red when I test this stuff after adding it in. With liquid-based nutrients, it doesn't change PH that much... but this stuff does. So make sure to buy enough of the PH raising solution to go with this. You'll use maybe a cup per 8 gallons or more... from mixing in only 8 teaspoons of this stuff. Yikes.

I had bought a 2lbs bag that made my plants grow crazy fast. So I invested in a my 16lb bag of this and this larger bag doesn't seem to be doing much of anything for my plants.
