Fear nothing my friend! I will give you a lesson on powdery mildew! Let's go over a few things first okay?
Mildew spores can be found everywhere. Powdery mildew is a common problem for both indoor and outdoor growers whenever the temperature and humidity fall into its favored range.
Powdery mildew is most likely to attack young leaves, up to two or three weeks old. The infection spreads over the plant and spreads to other plants in the garden. It can affect buds, stems, stalks, and leaves.
The appearance will look like it has been dusted with flour or confectionary sugar. After being infected, the plants turn prematurely yellow, brown, and eventually die. If untreated, black specks can arise in the white powdery mildew. Buds will have a stale, moist smell, and will be coated in the powdery mildew.
Powdery mildew in vegetative growth is easier to treat than in the later stages of flowering. Quarantine all new plants in a separate area where they cant infect other plants. If your plants get infected to far into the flowering stage, it is probably too late and the buds already have spores on them. Germicidal UVC light are great to use and kill powder mildew spores that become airborne. Ionizers also work well! Remember if you see any mildew STOP FOLIAR SPRAY COMPLETELY and keep your humidity under 50% as well.
To prevent powdery mildew in the first place you can use these products regularly: Ampelomyces quisqualis, bacillus pumilis, bacillus subtilis, compost and compost tea, milk, neem oil, potassium bicarbonate, sesame and fish oils, sodium bicarbonate.
JUST REMEMBER IN ORDER TO TREAT THE MILDEW THE INFECTED LEAVES SHOULD BE REMOVED FIRST, AND THEN CUT STEMS SHOULD BE TREATED WITH FUNGICIDE
After removing the leaves, you can treat powdery mildew with: Vinegar, bacillus pumilis, bacillus subtilis, cinnamon oil and tea, clove oil, copper, coriander oil, garlic, horticultural oils containing jojoba or cottonseed oil. hydrogen peroxide, limonene, milk, neem oil, ph up, potassium bicarbonate, sesame oil, sodium bicarbonate, sulfur.
I hope that helps! I was studying to become a botanist but then changed my major to biology, so I know a few things about plants! hehe GOODLUCK!
