You can wash them after harvest, get 3 5 gallon buckets of distilled or RO water, the first one will be your cleaning solution. Baking soda and lemon juice, this bucket should be warm water, the other 2 buckets are cold plain water. Vacuum all the webs and shit off the buds after chop, one branch at a time, dunk and swirl in the cleaning solution for 30 seconds, gently, then 30 seconds in each rinse bucket, then hang to dry. This will not take trichomes or terps away from your flower but it will wash the mites out of your flower. The solution ratio is 1tsp of each baking soda and lemon juice per liter of water, so about 20 each for 5 gallons. You can vacuum those webs off the live plant for now and finish her out so your time isn't wasted, but after harvest you will want to seriously clean that grow or they will come back. I got my mites from going into my outside garden and then going into the grow, pets will also bring them into the area as well.
Thanks!
