Hey,
Giving your plant silica throughout the grows will help make it stronger, healthier and more resilient...which will help fight off various things or not get infected.
However I would order a product called Green Cleaner (agricultural ...not household) it kicks pm in the ass and also kills off mites and keeps them away. Definitely a good use of money and effective. You can try other remedies, milk, hydrogen peroxide, various insecticide soaps...but if you want a sure thing. Get green clean.
👍
