Have you been able to visibly identify thrips on your plants? If you have, the yellow sticky traps work great to prevent re-infestation after you follow Stinky's advice. Hang them plant level and the thrips can't get enough.

I have had plants that would develop small holes in the leaves, both in vegetative and flowering, with no evident, external cause. There were no pests, no foliar applications. There would only be a few per plant and they never enlarged or seemed to cause any stress.
