    Persistent Ph problem

    I'm on my third grow, in soil, Biomix light with perlite... Current grow is AK48, PPP, Northern Lights, all femenized. Problem is high ph.. everything starts off great with a ph of 7 - I adjust that by watering with ph adjusted to 5.2/5.4. And that corrects the ph, according to the runoff...
