It could depend on many different factors, what is the recommendations of the product itself and are you using r/o or tap water and what is your starting ppm in the water. Are you asking the ppm of your solution you pour on your soil? Flood and drain coco filled pot or rockwool table flood to drain or ebb and flow? Or Deep Water Culture reservoir’s ppm?
