    SOIL Is this calcium deficiency ?

    Hello guys. Hope everything is ok.

    So i have this problem and i really don t know what to do anymore.

    First i thought it s nutrient birn..i flushed but the it got worst. Then i treated them for fungus but nothing happend.

    Can anybody please tell me what this problem is ? I am using nutrients from canna. Tera veg, rizotonic Nitrozime.

    I have 28’c humidity 60-70%. Running with t5 bulbs. Light running 24h.

    Thank tou very much !

    my first thought was maybe a root issue caused by the girls outgrowing their's transplant time IMHO...good luck!

      Thank you !

    The containers you have them in are really small. Could be root bound by now. I would transplant them into larger containers.
    What is the PH of your run off water?
    4x4 600w HID empty for summer
    3x3 400w HID with Bruce Banner and Skywalker Kush
    2x2 65w Quantum Board LED with 4 mother strains
    running all simultaneously for a perpetual harvests.

      Ok. I will transplant the girls asap. The ph is 6.0 - 6.2. I really hope this is the problem.

      Thank you!

      6.0 is a bit low for soil. That’s the run off? What was the ph going in?
      I would contact the soil manufacturer and find out what the optimal ph range is for their product. The soil I use recommends 6.3-6.8.
