    Hey all,

    Recently on a couple of my plants I’ve started seeing orange spots appearing on fan leaves. I’ve never seen anything quite like it:

    Can anybody help me figure out what’s going on here and how to fix it? :blink:

    Check the underside of the fan leaves for signs of bugs, if you rule that out, how has your PH been? And next what kind of water are you using, if RO, it could simply have a Cal mag issue. Remember, the problem you see today started a while ago.

    When I use General Organics line that happens with over fertilization. Too much cal mag I think.

    I have an 8 bucket DWC system, keeping the pH around 5.8 and the EC around 1.0. I use dyna gro foliage pro, as well as cal-mag supplements.
