Try 1tbsp oh hydrogen peroxide 3% with a tablespoon of baking soda and 2 dish soap drips of soap in a liter spary bottle. Shake well and spay on the leaves top and bottom. I also suggest doing a bud wash when you harvest. You can do that by 1 cup of hydrogen peroxide and 1/2 cup of baking soda in a 5 gallon bucket and mix well. Then do a double rinse in 2 other 5 gallon buckets. Clean buckets as needed through the process.

Is this powdery mildew?Is this powdery mildew? I am seeing some white spots starting to form on the underside and top side of lower fan leaves. Would adding an oscillating fan help prevent anymore white spots from appearing in the future or will I need to apply neem oil or something?

White powdery mildew in late flowerWhat's your best remedy to remove it on flowering plants? I just found it after I had forgotten to replace on of the fans when I left them for a few days.
What can I do to remove it as quickly as possible without ruining the buds? I'd prefer not spraying them with milk.

Mould? Mites? Nothing?OK, re asking this question with better photos as I don't know how to add new photos to an already posted question. Posssible mold? Spider mites? Leaves have looked kinda similar since I got them. Any ideas? To me it looks like maybe mites but I dunnno.

Possible mold/mildew - I ask a ton of grow questions but figure someone else might learn if I do well or f up. Good community hereMildew? This has been on certain leaves of my plants since I got them so I didn't think much of them. But as I'm about two weeks into flowering, I want to see if this is possibly an issue. Have okay airflow in the tent but could be better. Humidity is 55% atmosphere. Thoughts?

I need help diagnosing what this was. I already cut off two of the affected leaves on the Kmintz, but other leaves have small amount of the same substance on both plants. The brown spot in the first pic ended up turning into a hole because it was so dry. Is this powdery mildew?

Powdery Mildew near end of floweringFor the last few days, powdery mildew is starting to form on the leaves and some of the buds. I've cut where mildew was, lowered humidity to around 45% and increased air circulation by focusing a fan on the plant but it is still forming. Anything else I should do?
