    Any other pertinent info?
    Ph of my tap water is 8+, after adding nutes it brings it down to 6-7ish...
    They were repotted two days ago, from 1gal container, roots were everywhere...
    Brown spots started apearing the day after, mostly on older/middle leaves...
    I have used regular tap water with 8+ph when watering after repotting,didnt want to over nute, I think I might have messed up with the ph of the soil...
    from what im seeing it might be a cal/mag deficiency due to lockout...but not positive..
    should I flush them with ph ajusted water?
    Any other tips?

  3. If you want your plant to improve, sometimes you have no choice but to flush if ph is skewed. I notice you gave attention to ph in your water and nutes, but you mention nothing of ph run-off. If you'll measure ph run-off and adjust soil ph from there your girl will improve. Damage is permanent, Ca spots will remain.
