I have been battling with thrips for few months now and couldn't get rid of them i tried spraying pyrethrum, neem oil i treated water with Bti and nothing worked until i got hold of some spinosad which is not easy in the uk, i have given two applications of spinosad 5 days apart and have some azamax on order which i will alternate weekly and all seems well so far i cant find an adult thrip or pupae on any of the plants. the problem i have now is my purple maroc, frisian dew and passion#1 mothers dont look to good could they have a virus after the thrips. 10 weeks from seeds now in 6l pots canna coco canna coco nutrients e.c 1.0 ph 5.9. i have attached a few pictures so you can have a look.
