Insecticidal soaps often say they kill both thrips and mites on contact (check the bottle), so it may be worth treating your collection frequently (1-2x a week) with that for several weeks. Thrips are really a pain, because they lay their eggs in plant tissue and will keep coming back until you get all of them as they hatch, since most things only kill them on contact (and even those things should be rotated since they tend to build up resistance). One of the users here finally got a heavy duty thrips-specific systemic insecticide that she will get a packet of to whoever may need it (if she still has some!) and it takes one or two doses to kill them off.As far as being sure of which it is, I'm not horribly experienced but just had some thrips myself and your issues definitely look suspicious. The dimples on the underside of some of the leaves make me think of mites too, with my untrained eye, though I suppose it could all be thrips. Can you inspect with a magnifying glass? Those flowers should have some thrips in the crevices if they're there.Ever tested for viruses? Some of that damage looks suspicious too... I hope others with more experience weigh in
