There is a chart in the FAQ section that show the available nutrients at different Ph levels for both soil and hydroponic gardening. DL it to you desk top for reference.

That should answer your Ph question.
Zandor Reviewed by Zandor on . A few questions about PH..from a rookie PH questions 1) What is the proper PH and just how close do you need to be to that number ? 2) If PH is too high how do i bring it down ? 3) If PH is too low how do i bring it up ? 4) Is nute lock the main concern with an incorrect PH level or are there other effects from your PH being off??
