Powdery mildew

Hey there BigBucket, your problem is quite severe unfortunately, what you really want to do is fix the problem in a sustainable way so the soil protects itself naturally. Now , again, this outbreak is quite severe so dont get your hopes up but basically you want to add bacilus subtilis bacilus thuriengiensis (BT) and trichoderma keep adding them around sunset time in the soil and on the leaves of the plant in a spray (the BT not the rest) and it should cannabalise the PM starting after the first week, and after up to three weeks treating it intensively you can start falling back towards an every ten days schedule. Do that and the PM should be at least starting to get under control in 3 to 4 weeks. hope this helps ! 🚀

Remove White Powdery Mildew from leaves – Get some water (tap water works fine) and some paper towels. Wet the paper towels and use them to gently wipe the mildew off the affected leaves whilst being careful not to jostle any leaves with spores on them. Using a wet cloth will ensure that more spores stick to the cloth instead of becoming airborne. Note: While it isn’t necessary to use paper towels, their disposability helps to curb the spread of spores from one leaf to another. Ensure plants have proper airflow and ventilation – Even if you have absolutely no airflow or ventilation in your grow room, having just two fans will drastically reduce your chances of encountering WPM while also benefitting your plant’s overall health. One fan should be oscillating if possible and should gently blow air over your plants. All the plants need is enough air to gently rustle their leaves which will make it hard for WPM to settle down. The second fan should be in your grow room pointing outward to exchange old air with fresh air. Having a fan pointing out of your grow room will force old air out of the room, and in turn, pull new air into the room. At this point, you’ll have new air coming in, being used and circulated, then kicked out. Keep in mind that two fans are a minimum. Treat the infected plant with one of the options below to kill spores prevent future growth – Mix up your treatment of choice in a clean sprayer/mister. We recommend Lost Coast Plant Therapy (1oz/2btsp per gallon of water) or GrowSafe (2oz/4tbsp per gallon of water) as a safe second option. Make sure to consult the instructions on your treatment of choice to find the recommended dosage. Wait until just before your lights for off for the day and mist your (newly-cleaned) plants. Get all the leaves even if you don’t see WPM on them! Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.

40% homoginized milk to 60% water mix and spray. You may need to repeat a few times to kill remaining spores. Cheers
