Make sure when you use the PH meter test five or six different area's and depths of the soil and find the average. I have found that different area's sometimes have huge fluctuations in PH so it's best to test a few area's and then calculate to find your result.

That's one of the problems with using soil. In hydro everything can be accurate to the point and things can be dialed in perfectly for each strain you grow. Even so, I find soil much more forgiving and if you are doing it for a cash crop, it's the only way to go. Some will disagree but I have many reasons why, but I won't bore you all to death as I am starting to ramble now and this has nothing to do with this thread. I'm done. Good luck!
