Powdery mildew? is there an organic way to treat it? Milk? mild vinegar solution I have tried the milk spray. It may have knocked it back a little but i'm pulling leaves every day and keeping a close eye out for it.

Hey there so there are many treatments for PM. Like you mentioned milk is good something about lactobacillus works very well. Ive heard vinegar as well. Any silcon solution is a great option so a calcium silicate or especially potassium silicate. Theres some products called "pre-vent" and its special towards powdery mildew and botrytis(grey mold). Products that contain sulfur or bicarbonate are good, such as neem oil has sulfur in it and that helps it to attack all the spores and prevent the colony from reproducing. If you do the milk option which is one of the best non chemical methods i would do about a 1 to 10 ratio with your mixture. The bicarbonate option is essentially baking soda highly diluted, in that mix you can also add a very small amount of vegetable/mineral oil to help counteract the sodium. Best of luck. Check out the kis organics cannabis cultivation and science podcast, its got a great episode all on PM. Happy growing and flowering.:v:

Hello @emmett! You can use a lot of stuff like milk,potassium bicarbonate, garlic,cinnamon, propolis and many other . But no matter you are going to use if you don't fix the temperature and the humidity the problem will never go away. Happy growing ! :facepunch:

Neem oil is supposed to be best for treating powdery mildew. Pretty sure a 4:1 ratio water to neem oil is the recommended mixture. Good luck :+1:

hi, The best is to avoid situatoins the mildew likes to "grow" if there less airlow, to much humidity, poor ventilation and leaf to leaf is getting worse. you can get rid of it with

Milk (1:9 ratio of milk to water)

Baking soda (2 tablespoons per gallon of water)

Neem Oil (4 teaspoons per gallon of water)

Hydrogen Peroxide (1 teaspoon per gallon of 35% H202)

SM-90 (1:5 ratio of SM-90 to water).... look for the "weapon of Choice" and for reading it a little article for you....

Hi @emmett! Neem oil, milk, potassium bicarbonate, garlic, sulfur [...] will do te job. Since you're in late flowering stage, I'd recommend to go with garlic which contains a lot of sulfur. This works best when combined with rubbing alcohol or neem oil but I won't risk to pollute your buds, so maybe just a few drops of neem oil mixed with crushed garlics and water. To avoid bud pollution I won't use a foliar spray but I would do it with a sponge, delicately applying the solution onto the leaves. This will require some time/efforts but you'll ensure not to ruin your buds. Hope this wil help, keep us up-to-date and happy growing :facepunch:

hey man most of the effort should go into prevention for example air flow a clean environment, not growing your pot in cardboard boxes :laughing: anyway that vinegar solution will work but you got to mist till it does keep it going every few hs you want to be done with it 100% before you cut and dry
