I believe I have mites but it's the last 9 days of flower. I got rid of the fan leaves where they were cause I really don't want to spray anything at this time. They just showed up maybe 40 days in. The leaves had white specks on them.
You can use a fine sprayer on you hose and use water to wash them off. Then put a fan on your plant to dry it off. best you can do repeat if necessary. It rains outside and growers grow outside so it basically a natural way to clean her. Good luck.👍
They can handle the 9 last days without spreading because spreading something on your buds means : create a good environment for bud rot issue. On the other hand they reproduce so fast that I would advise you to check under the leaves every days and manually removes much as possible with a tissue
Sorry to answer late but you got it right don't spray anything on plant fro week 2 of flowering till harvest. Also all u can do is try to kill them one by one, cut out leaves, etc... But as long as u don't see webbing you'll be fine.
