    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.

    My run off is about the same and I found myself wondering the same thing. Good question!

    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
