My ph meter starts to blink every time my ph is above 5.5, but I heard the best ph for hydro is 5.5-6.2, but I'm using a aeropnic sytem. I was told between 4.5-5.5 is the best for my system. Can some answer this for me ? Also what the recommended pm level for a budding plant.
PPM is best set for 890ppm for flowering with most mj plants, this number does not count the ppm that is already in the water. Normal tap water is around 150 to 250 ppm.
As for ph, I thought is was 5.3 to 6.5 but I do a ebb n flow. Not sure with aero.
