You could ignore them.........mite damage will be minimal at this late stage..
Otherwise predators may help, but if you only have a couple of weeks to go, I doubt they would do anything much that will change anything in real terms before harvest.
I would strongly advise against spraying buds with ANYTHING this close to harvest, no matter how much the spray may claim "to be completely safe".
Predators would be the best option if you want/need to do something to help.
