Found a thrip?

I only found one, and I haven't seen it in 3-4 days now. There seems to be 2-3 leaves of damage and small flies living in the soil, though I haven't seen maggots. The flies have been there at least a week or two and I haven't seen them do any damage so far. If I'm in the fourth week of flowering should I just let them be? or find a way to kill them? thanks

Blue sticky traps and maybe some neem but that's critical in flower.

As said, if its defo a thrip..
sticky traps, neem, pyrethrum fine to use in flower. Will slow you down by a few days.. But safe for flower. .edit. Its a contact insect/mite a cide.

also dont let it be,,thrips a very bad when they get established.
