    powdery mildew... get your humidity levels as low as you can first.. dehumidifier,, puta lid on the resi..
    then you can use a sulfur burner if you have avoided using any oil foliar sprays. burn sulphur... baking soda and water mixed and sprayed also works by changing the ph on the leaf surface... i like einstien oil .. neem oil but make sure you get your humidity in check first..

    cut off all leaves infected cause it spreads fast.. even if you have to remove whole plants.. there are lots of ways to get rid of it but the humidity is the issue.. pm sucks if its out of hand

    Had the same issue read an article on applying a 1 to 9 parts milk and water solution I'll see if I can find the link.

    Increase ventilation, the faster you can change the air in the room with low humidity air the better. In soil, water in the morning when the lights turn on so that water can evaporate, do not water at night before lights turn off, because it will be wet. Ventilation all the time and watering early in the day will help a lot to keep humidity down, and pm loves cool humid nights with no wind. In bloom, the same conditions that favor pm also favor budrot, which sucks. This can eat a cola from the inside, turning it to brown mush, and can happen in 24 hours. Make sure you pull buds apart and back from the main stem in really dense spot, and get air in there so water doesnt get trapped.

    i got lots of shit for saying the same thing a few months back.. but it worked when i tried it. and it doesnt spoil and turn to mold or anything.. it dries with a shine like neem.. and it doesnt smell like rotten milk..

    How much did you use and how many times did you apply it? I am ready to try anything if milk works I will try it! Thanks

    what about cutting leaves and infected parts off during mid to late flower will that stress plants to the point that i should just get rid of the plant instead. Ive been growing in this particular environment for over a year and a half and this is my first mildew outbreak. And when cutting the infected leaves off should you disinfect the cutting implement with anything between cuts and if so, what?

    Hey doniawon, are you saying that you shouldnt run a sulfur burner if you have been spraying oily foliar sprays?

    doniawon Well-Known Member

    yes do not its will fry your leaves

    well you have to understand why it works. Milk is slightly basic so when spraying your plant the leaf surface ph will change becoming a unsuitable environment for the mildew to grow.

    milk is used for the big agricultural grows all the
    way up to harvest
