What does ppm mean? This is an abbreviation for "parts per million" and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing. ppm is an abbreviation of parts per million.

Because autoflowers will stay much shorter than regular plants, their nutrition doesn't need to be as high. Also, you want to be sure to ease your plants into their feedings. For example, if the peak PPM for a plant says 600, you'll want to start from your current PPM (for example sake, we'll say 300 PPM) and slowly go up each feeding. Definition: One PPM means one (defect or event) in a million or 1/1,000,000.
