Hey Zoltrix, you subtract what your tap waters ppm was from the total your meter tells you, to find out how much of the total ppm, are the nutrients you have added! The feeding programs you get from your nutrient manufacturer are telling you how many pmm you should be feeding your plants of their nutrients! You subtract you tap waters ppm from your pens total, and add your nutrients till you reach the ppm your chart or feeding program is telling you to feed! Happy Growing My Friend!
