  2. I wouldn't go full strength with that big bloom, 1/2 strength on nutes to avoid nute burn. In my opinion that is very minor nutrient burn your seeing, other than that your plant looks really heathy.
  3. Ya, cut back on the nutes dosage.

  4. Thanks for the great advice guys
    the problem hasn't progressed since Monday so i am just going to dial down the nutes for now.
    and stachi your grow turned out excellent, I only hope my girls turn out half as nice as yours ;)
  5. Keep us updated !!
    Good growing

    Some early year diesel ryder outside!
