      Tersky Thanks for the link. That might be the issue. The link mentions red stems which all 4 ladies have which I had thought might just be normal to the plant (Big Bang autos).

      Lights are in a 18/6 schedule since they are autos.

      I did a fresh water change (ph’d and nuted). I’m wondering if I’m not adding enough nutes since I’m feeding at 50% of the manufactures recommend dose.

      I should also note that she has tiny pre-flower buds with pistils just showing, so flowering should start soon. Should I add a small dose of flowering nutes to the solution to help bring up the phosphorus?

        Yes. ASAP!! When the pistols start showing then it is in fact flowering and needs it's flowering nutes. Give it bloom nutes according to recommended dosages.

          I had the same problem before with burnt ends and tiger stripped leaves. I also noticed some discoloration in my roots during a reservoir change. I bought some stuff called orca microbes. It’s kind of expensive about 35$ but it only took a week for my roots to double in size and be pure milky white and in another week no tiger stripes or burnt tips on my leaves. I only use 1.25ml for my 4gal reservoir so it will last a long time.
