Seedling question - white powdery mildew part 2

Discussion in 'Growing Marijuana Indoors' started by iaw, Apr 9, 2021.

  1. On another post that people said I didn’t have mildew on my seedlings and maybe I’m being paranoid (hope I am) but the white dots wipe off and come back and seem to be expanding.

    last time I ask ... but can I please get some comments on the photos

    Either at 1 tablespoon per gallon of water. Drench spray once a week every week start to finish.
    As an outside growers this is just part of what is needed to get a clean crop.

    All the Bicarbonate does is raise the water PH high enough to kill the mildew but not harm the plant.

  3. Pm wipes off ...lucky you

    reduce water I'd think hard about using any strong alkali ph'ing your soil

    reduce water ...apply lite neem oil ..your plants are very young
    so are tough and can easy handle this fungi ......pythium is a different story

    good luck
     
  4. Mix one teaspoon of Neem oil and one half teaspoon of soap, not detergent, in a qt of warm water.and spray it on until it is on until it is dripping wet. Powdery mildew can’t survive it.
     
  5. get the air moving . Fresh air in and out . You will never get power mold .
    You can just give them a bath plain water .Run a fan 24/7
