I cannot make out bugs due to all the perlite and such. If you find the need to eradicate the buggers, then use Food Grade Diatomaceous Earth. Only Food Grade CODEX
I agree I’ve had good results so far with d e food grade. In the past I ordered some stuff off of Amazon called SNS 209. It’s a systemic application but can also be used as a spray. That stuff worked but took a couple weeks. Follow directions on bottle if you buy any. Good luck! I’ve had thrips or aphids in the past. Came from overwatering in my soil.
Tractor Supply sells food grade DE. It’s in a square jug back with the animal feed.
