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.

Help the HermyMy 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 😵

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!

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.

White Spots on top of LeavesI 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?

Minor damage to a few leaves found today - what is it?I am trying to determine the cause of damage to a few leaves that was observed this week. It may be two different problems. On a few leaves, I see brown spots which may have originally been white. On another 2 leaves, I see a burn hole through the leaves with brown edges.

Best treatment for combating white powdery mildew at first sign of it? I used a non toxic sulfur spray with some defoliation of the more prominent leaves, especially any close to a bud site. It helped keep it at bay but had to be reapplied weekly and still fighting it daily.Week 11

On my other grows I've had some issues with pests. The worst was white powdery mold, but I've also seen leaf miners, aphids etc.
I want to treat this plant pre-emptively with something like BioNeem. Is it safe to do that at this stage of bloom? Can you recommend safe alternativeWeek 6
