its parts per million, it has to do with how much salts are in your water. salts can be found in nutes or in water out of tap. the amount a plant can use depends on size of plant

depends on how much they can uptake.. some plants are heavy feeders and some are not..typically when u see burnt marks on a plant that is cuz the ppm is to high ..in your case you growing autos.. ppm should range between 500-800
