Help: root PH flush or something else

  1. Help,

    This is my oldest girl northern light auto at about 45 days and she's showing these cal mag deficiencies for about a week now, i have her 2 mild flush with cal mag added and water PH at about 8. I got runoff PH of about 5 after which i have it another liter of water maybe. I did not take PH again and thought it would get fixed, I'm skeptical giving them a flush at this point, so is flushing the only way to go? What else can i do to fix root zone PH? H2o2 mix? Or both, flush with peroxide mix of sorts?

    The single leaf shots are towards the lower part of plant. [​IMG][​IMG][​IMG][​IMG][​IMG]

    Check out my first grow log:

  2. Dolomite lime will level out soil ph while providing some calcium and magnesium. Just work a few tbs into your top soil and water. It should help
