    Hello world- Not sure what's going on here.

    The issue is mainly located on the top of her. Here's the set up:
    Coco medium
    Kind LED 750 in a 4'x8'
    Was using Canna AB, but will be switching to Advanced 
    Rock resinator 
    Sugaree
    Calmag
    and when applicable, PK, Bud Ignitor, and Overdrive. (with rock, and sugaree included in feedings).
    (I have Big Bud, but don't use it...)
     
    I always PH it at 5.8. Always. Temps are always around 77*F. 
     
    The leaves have always pretty much done this towards the last 2-3 weeks before she's cut. Perhaps there's too much of something added in that concoction? 
     
    My first time posting! Thank you in advance for any and all comments/feedback.

  2. Does this help at all? ImageUploadedByGrasscity Forum1434218997.272892.jpg
     
  3. Maybe a Zinc deficiency? 
     
  4. Maybe I think that's a rare def tho, I'm not very good at diagnosing plants, maybe somebody else will chime in
     
  5. Any shots without the led?
