    Background info———
    I have been struggling with Nitro tox and this I haven’t been feeding any N but it has since cleared up. The problem being that I am using Nutes that come in a kit so if I don’t use anything with N then it’s probably missing a shit ton of micros it needs aswell so I’m assuming that is the isssue so when she dries up I can give her a good feeding and hopefully all will be fine, however I would like a second opinion because Ive never had this issue before. Your looking for rust almost looking colouration on the leaves. IMG_2531.JPG IMG_2533.JPG

    • Disagree Disagree x 1
  3. Slight excess nutes ....no biggy

    maybe feed 50% less for 2-3 weeks

    of concern is the red

    in most cases its falling temps or poor temp control

    see anthrocycline or stalled sap!

    see to your temps at lights out

    good luck
     
  4. Check your PH

  5. What exactly are you using for nutes? I use general hydroponics 3 part. I dont use the "grow" bottle though, just the micro and bloom. I use epsom salt every feeding at 1/4 teaspoon. You say you ph balance everything. What is the exact number?
     
  6. A little under 6.5
    I have the same kit, due to the N problems I only used the bloom last two feedings. I don’t use epsom salt only because I don’t really know what it does and I don’t wanna add more ppm and not know what I’m putting in my mix
