Thrips are pretty easy to kill unlike mites, Rosemary oil as (is pyrethrum) is fairly effective on Thrips and very effective on mites, Thrips start bottom up , they like cooler temps and higher humidity, still air, spray the lower 3rd of the canopy stems, lower leaves etc with rosemary oil 20ml per litre with a few drops of dish washing liquid (shake well). removed the bottom leaves and destroy before spraying. spray just before lights out and allow to dry below lights on. increase air flow with a oscillating fan under the canopy . Start with the environment, blow air through your lower canopy.
once the Crop is finished , nuke the place with 40 ml of 100 % rosemary oil to one litre of water and 5 ml of dish washing liquid. all surfaces.
a side note pyrethrum can and does burn soft growth, rosemary wont if its dry before lights on, run a oscillating fan in the dark
