Need Help, Spider Mites/Azatrol

I recently returned from a trip and found that i had spider mites. Though not as bad a case as ive seen before when helping others with their crop but, the problem still exists. As they say, where there is one spider mite, theres a shit load of eggs... im going to be using azatrol to try and control it but had a few concerns....

1.) Will it mess With my buds in any way if it comes in contact?(three weeks in flowering in greenhouse)

2.) Can I still apply nutrient formulas while using azatrol?

1.No

2.Yes
