    Calcium, Magnesium and Iron are generally much more available in soil than hydro, which it must be added. Most soils naturally contain some level of the three. In hydro, unless your base nutes have enough, you need to add extra calmag. I find that in hydro I always have to add calmag in mid flower or I get a bad deficiency that appears to be many different deficiencies.

    Looks like root issue .... Since you just fed , i would mix up a foliar spray of CalMag.
    The main symptom ( to me ) is the CUPPING.

    Is the grow area ( floor area ) always looking damp , or mildew ?
    Just asking.

    I probably wouldnt risk a transplant while she is ILL . It may shock her and you will be worse off.

    Have you checked out LEC/CMH lights Insomnia? Run cooler than HID's, but still looks like one, and has a vastly improved spectrum compared to any HID....food for thought. Good luck bud.

    They will never recover once they claw, but if you fix it, the new growth will not be clawed.

    I posted a week ago or so about my plant leaves yellowing and son on and i discovered that the ph of my runoff water was 7.7
    how can i drop it down just a PH'd flush? the flower seems to be doing fine but the leaves are taking a beating. ALSO I WAS A DUMMY AND PUT THIS PLANT IN MIRACLE GROW and i know that was a big mistake .. but is there a way to save her? I watered her 2 days ago with a half gallon of R.O water PH'd at 6.2 with CAL-MAG no real changes

    Not sure if that's a auto or what but if it's a photo you could pull it outta pot get as much MG soil off the roots with out killing it maybe dip the roots in a bucket of water to get rest of dirt off then put in GOOD soil that might help then feed with a 0-15-15/something with little to no N well good.luck

    She is an auto but that seems a little scary to uproot her .. iv been dosing her with R.O water PH'D at 5.8 to try and flush out that crappy soil ... she doesn't have a long time left for flower so i think ill just try to keep her as healthy as possible with good water and TLC her flowers are pungent and becoming coated with resin .. i kinda think she'll do fine up until harvest. But on another note have you ever done this before ? Uprooting and rinsing the roots?
