demoreal Reviewed by demoreal on . P H DOWN I filled my res today to start my little ladies in the ebb n grow system. My ph is 7.04 I have already put in the nutes I'll be using and was wondering about this ph down. When I add it does it take long to take effect? I guess I'm saying how long should I wait to see if I have added the proper amount? I have the G H up and down liquid. I am using Ionic Hard water nutes at 1/2 strength. Any and all help on this would be great. Ive also heard that these nutes will drop P H after a day? any truth Rating: 5
