POWDERY MILDEW

How to treat powdery mildew? Lost 1 plant because I didn't catch it in time (only 4 weeks from harvest). Pulled the other plants out and used warm bleach water and washed the inside of the tent, lights, and fans. Sprayed the other girls with milk/water mix. Is there anything else I can do just to get them across the finish line or are they doomed?

        And defoliate to improve air flow in the canopy.

        Just about the only things you can do this late in flower.

        • I agree with the answers above but that is more preventative, to get rid of it assuming you already have it I sprayed with 3% hydrogen peroxide and did it a few times about 3 days apart. It seems to get rid of it even on out door grows but if you dont solve airflow it will be back in force.

          • You can keep it fought back by mixing 1tbs of vinegar in a quart of water and spraying leaves top and bottom. Personally I use apple cider vinegar but white will work  I also use a drop or two of dish soap. Wash your plants when you harvest.
