its usually close to 6.5, usually I only need a little adjusting ph. of water. I think one bucket was 6.4 but I previously guessed and added a small amount of down ph. my other bucket untouched was 9. range I think. I think I'm all good. I just failed to keep my ph. pen in good condition. I sometimes go years without a grow so things fail and I have to relearn. Thanks. I'm getting another grow set up hopefully I will succeed this time. I'm in bad shape my past three grows failed to yield so things are getting desperate. Can't afford to fail again
