Newly reformulated to a less concentrated 25% strength, so it's easier to use for novice growers - less chance of over dosing. New lower price, too! Essentials pH adjusters work simply by altering the pH of a solution. If the current pH is at 5 (slightly acidic) a solution of alkaline (pH UP) is added to raise the solution to the desired level. This also works in reverse.
