Personally I haven't had to deal with mites.
But there's many ways to go about tackling them.
Some ways work and some don't. All depends how far it has gotten. The whole vac thing. Hmm, you aren't meant to be even handling bud as you off trichs and that. But idk I haven't had to deal with them
But what I have read. There's a few things you can do to make it hard for them to get around to manage it better, maybe you won't be able to get rid of them but lowering the population will help if you wanna bring it to full harvest and look into bud washing.
You can take away fan leafs and clear growth away and make it hard for them to move around.
You want to look underneath for eggs. (This is some job to do) So it's really best to just grab the leafs and wipe underneath top and bottom. Or get down on your knees and check out and wipe down either way lots of wiping down.
To combat the mites. If you don't have anything. A spray bottle after you have fucked up their paths and making it easy for them to move around you can spray your plants and it'll spray them off but you wanna start from the top and spray closely to clear out and drop that pop. Any then if you have any neem oil apply or AMC spider mite leaf wash. I just got canna cure idk how good it is for mites but you need to look up different ways to combat them with the tools you have on hand you try them methods as you'll be given lots of answers but you can only work with what you got. So check out how to combat mites with ?,?,? (Whatever you have on hand)
Good luck.
