    Mag. Def & Neem Oil

    My girls have developed a Magnesium deficiency over the last 2 or 3 days... evident by the leaves. I've tested the soil PH this morning & it's 7.25-7.3. I'm wondering whether this is a little on the high side & should really be 6.5 ish for optimum Mag absorption from Nutes? I have some PH down...
