Thrips!! Week 4 flower

So I've jus found what I belive are thrips in my 4 plants I have growing..I'm on week 4 of flower and looking for some advice on what to do with been this late in flower..I've been advised of a pyrethrum powder to make up and spray over plants but I'm worried this may damage buds.. any advice or recommendations..thank you all

Personally I woukdnt spray anything that far in flower.
If plants are still ok Id ride it out then get spinosad and treat veg and everywhere.

So ride this grow out then if it happens again then use some form of spray...thanks for your reply mate my first time growing so fingers crossed all goes to plan...I do plan on checking them every few days given leaves a rub with fingers ect to try save me from spraying...really don't wanna effect the buds as looking very good and tasty haha

I had good results using Green Cleaner mid-flower. It's non toxic and they say it's safe to use right up until harvest, although I wouldn't push it.

Make sure you spray the underside of the leaves as well as the top. I avoided spraying near the buds.

I'm now thinking of using a solution but rather than spray im going to wipe tops and bottoms of leaves and all stalks wer thers no bud close to minimise any effect on taste ect
