FIrst of al spider mites make white dots form on the top of leaves. You do not have a spider mite infestation.
Mealy bugs it is.
First of all, since it appears you are in flower stage I would not touch my plants with ANYTHING chemical at all. It takes up to 28 days for UV rays to breakdown the toxins.
DO not smoke the chemicals for your own good would be my advice.
What would I do?
Let them go. Pick as many off one by one by one.
Your predators will need several weeks to get established to begin with so odds are they will not make a difference in time to alter your yeild. The time for predators is prior to flowr, not during, as they can take 4 - 6 weeks to conquer.
Neem oil does not kill most pests, rather, it makes them sick and inhibits sexual activity. As you apply the neem oil every 4 days, after about 4 or 5 applications you have effectively interupted the reproductive cycle and there are fewer mites to deal with.
At this point I would let them grow as is and just hand pick what you can. It all depends on how many more weeks you have to flower, but you do not appear to have time.
Finally, if you can contain them, remember the pant will react to infestation by emitting more resins. It is what the resin is for probably.
I had one plant I completly let go with spider mites and by the end she was covered in a web.
But Gotdamn that was the strongest smoke I ever had. Grown right next to same strain plants that I battled 24/7 figuring this pest problem out.
Good luck...but dont smoke the chems!
