    Growing lemon haze sativa in 25 gallon smart pots of coast of maine stonington blend with perlite. The plants started to turn from a healthy dark green to discolored / bent tips about a month ago after I what I believed was nutrient burn.

    The twisting/curling and "claw" at the end of leaves suggested that was the problem.

    I was using alfalfa meal, kelp meal and neem seed meal. Added 1/4 cup of each once per month, but then when i did it after a quicker two week period, the problem started to emerge.

    So I watered a lot, flushed it out, and still no progress. It has been over a month since I added any nutrients.

    We've had plenty of sun.

    Leaves are bright/lime green.

    Is this actually a nutrient deficiency instead? Other?

    Any help greatly appreciated.

  2. If my only two choices were either nute burn or deficiency, I'd guess deficiency.

  3. If that’s all you’re feeding it, it’s prolly deficiency but are there fungus gnats too?
     
  4. I would at least topdress something in for calcium like oyster shell powder, crab meal, gypsum, biolive, etc.
     
  5. I haven't noticed any potential fungus gnats but will take a closer look.

    I think i will top dress with the alfalfa, kelp and neem seed meal and see how it responds.
