The ph of my runoff was 5.5 should I adjust the ph of the water to 7.5 next time? Usually I adjust it to 6.5. Sent from my iPhone using Grasscity Forum
My run off is about the same and I found myself wondering the same thing. Good question! Keep growing till the wheels fall off!!!
Generally you test the run off and the water you put in to find the root zone PH. I would say go 7.5, but I'm a new grower and have never tested my PH in my grow lol. Experts, chime in?
Yeah go for 7.5-8 but it takes a lot to bring it up. I had to use almost a gallon to get my 5" pot up to 6 from 5. Was using water with a ph of 7.5-8
