  1. At F 56 grandaddy Purple. Noticed burned tips a couple weeks ago and then this week this. Temps have risen to 80's this week.

    Coco w perlite
    Floranova bloom
    Liquid koolbloom
    Silica
    Call mag
    Ph 6
    Feed every other day.

    Ppm runoff 2000 plus!!!

    Plenty of amber I could cut. Thoughts?

    Did a 5 gallon rinse w pH water. Ppm down a bit was 3000 at first.

    Thanks

  2. What's your ppm going in?
    Never flush with plain water in coco - use 1/4 strength nutes.
     
  3. In has been around 1100.

  5. Seems like a lot of nutes to me.
    Try using this.

  7. Their floranova dtw chart shows 5ml/g so I've been over feeding by 50%... No wonder

  8. A good rule of thumb if you follow the bottle is to use 1/2 of what they call for.
    You've been feeding over double according to the feeding chart I attached.
    The chart calls for:
    2ml Calmag
    2.5ml Micro
    4ml Bloom
    You've been feeding 10ml bloom.

    Not surprising you have severe nute burn.
     
  9. Buds look great what do you think I should do till harvest? Follow the chart or even less?
