Hi
@NullHypothesis! Isolate the contaminated plants in another room if you can, otherwise the colony will spread and invade all of your babies. Predatory bugs will help you to get rid of those mites, but you will need to work in a closed environment, this usually leads to heat and poor airflow issues, which are the perfect conditions for mites to reproduce and lay eggs everywhere. So before running into this approach, make sure your setup will work within those conditions. In this situation, I think I would continue the chemical treatment for 2-3 weeks with a good airflow and cold temps, then close the environment (if your lights don't produce too much heat + if you have enough fans inside the tent to create a slight breeze) and release the predatory bugs for 2-3 weeks. This should work until harvest but remember to clean and re-clean your room after this run, those bastards can hide anywhere and come back at anytime if your room is not perfectly cleaned. Hope this will help, keep us up-to-date and happy growing 👊
