PPM (Parts-Per-Million) is a way to measure amounts as small as 1/1,000,000. What this means is that if we have 1,000,000 grams of liquid (1,000 liters) at 1 PPM then the liquid contains 1 gram of product.
Super-Grow has a PPM calculator and for most products there are detailed detailed instructions on creating a solution for the needed PPM.
