Slow crawlers on coco

I went to the pet store and bought some unbuffered coco coir bricks and used it for an auto seed. I knew nothing about buffering coco cause im a noob but I have been giving cal mag and it is improving. I was told that the slow crawlers might just be eating the coco and not harming my roots, put there in egg form by the coco brick manufacturers to help with waste disposal from reptiles and such. The bugs are only visible after watering in the moist spots on top of the coco. They are white/transparent in color and shaped like an aphid or mite and barely move at all.

My question is, should I treat the coco with some sort of pesticide now before it is too far into flowering incase they are root aphids?

I do see the occasional hypoaspis miles bug or some type of predatory mite that runs around the top of the dirt and flower pot very quickly so they could also be predatory mite young?

We cant help you if we dont know what it is. Therefore we need a picture. Take one and put it on a piece of paper under good lighting and take a picture.

Prob root aphids
