Try soapy water , it,s a good remedy if you can get all the leaves .
It drys leaving the mites trapped in the thin film of soap left behind.

Tetra if you put your plants back under your lights after spraying it would scorch the pistils.
So always spray your plants before they go to sleep.(light off)
It,s good to give em a second treatmeant a week later even if you can,t see any mites.
