Spider mite infestion

Plants have been flowering for two weeks and noticed whats turning out to be a major infestion of spider mites.Weba and all.I did notice some slight damage about 4 weeks ago and used Fox Farms"dont bug me" I followed the directions to the word repeating it three times in 10 days.It didnt work.
I just ordered 2000 predatory mites.Will this save my girls???I have 17 plants in a 4x4 area.Thanx

I'd love to help mate but i have never encounted them. (BUMP) hope you get some help.

i just had the same problem with my g13 plants. i went and bought some general might killer, diluted by half, and sprayed the shit of the plants every day since when the lights turn out.. still some mites but way better

Once the plant starts making bud you have to be careful what you use on the plants. The predatory mites are probably your best solution. You can also use neem oil to keep them at bay while your plants finish. Mites are a drag. I had them go through a crop and it was not pretty. Using the neem oil once a week will keep the buggers in check. I don't know if that is bad for the predatory mites. Check with the folks you got them from.
