  3. What nutrients are you using? And are you adding calmag along with them?
     
  4. Can’t be zinc defiency. Zinc is an immobile nutrient so if it was zinc deficient, only your top and new growth would be affected. That’s ruled out but I can’t quite tell what’s going on as of now, sorry brother.

    My guess would either be pH / nute lockout or more then like nitrogen, because you see how all the bottom leaves shades are getting lighter and lighter as it goes to the bottom? That’s more then likely a mobile nutrients defiency (opposite of immobile defiency so oldest leaves are affected from the bottom up, rather then vice versa) so my guess would be nitrogen, but could be lockout if you aren’t pHd correctly. But again, not an expert.

  7. Really?
    The leaves seem fine to me, but it’s their whole shade that’s changing color. To me, that reads deficiency or lock out.
     
  8. Sorry to blow up your feed but sammys question is relevant as well, because it could be cal mag also since coco usually never has its own cal mag unless added. So it may very well be cal mag since calcium is what helps uptake nitrogen and other nutrients
     
  9. Over watering.... in coco/perlite and fabric pots... on a plant with established roots.... outside in the middle of summer....
