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.

White Spots on top of Leaves I have discovered white spots on my plants. I think it is white mildew. From what I have read, the spores cannot be killed. You can only stop them a with pesticides or, if you are lucky, with a milk/water mixture, but you cannot remove them completely. What should i do?

Is this powdery mildew? How can we know for sure?Could these white spots be mildew? We could easily just basically shake them off, without any residue remaining. Currently only discovered in those two spots seen on the picture. In pics I find from mildew, it usually starts more dusty.. I also made one picture under the micro.

What are your best experiences for treating white powdery mildew? (4th week of flower)I carefully removed all the leaves with WM on it, but i want to spray the leaves to hinder further development of the mildew. What are your best experiences? I've read about milk solution, maybe citric acid solution with a ph of 9? Can i spray the buds too? Thanks for your help!

Help the Hermy My worst nightmare has become reality, my Pineapple Chunck (Week 7 of Flower) has developed male pollen sacs. What is your advice for me now? Remove the whole plant? Cut off branches? Harvest the plant now? The other plants are showing no signs, but I'm afraid it will be seedy 😵

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 flower What'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.

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 here Mildew? 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?
