What ph and ppm after flush

If I know my water ph and ppm, what am I looking for on the runoff ppm and ph? And after a flush, dry, then give nutes at 75-100%? Thx

Depends on your medium, soil or soiless. Near 5.8 for soiless, near 6.5 for soil. Ppm you’re looking for a runoff near what you put in. If your ppm is coming out much higher than what you put in, your plant is not eating. If it comes out much lower, you’re not feeding enough.


Perfect answer. Ty
