Can anyone identify this mite?

I’ve had nothing but issues during this grow and recently purchased some soil from a local hydro store, plants starting have specs of brown and white, brown edges as well as yellowing and dying leaves. I suspect there are other issues as well but I was advised to scope my plants for mites. This is what I found.

Does anyone know what kind of mite this is? Predatory, Spider, Russet? Don’t have any experience and my google searches haven’t really been helpful.

Looks like it could be a spider mite nymph? Does it have spots? The nymphs won't have promiment spots yet.

Or maybe a tick nymph, looks almost like a Cucumeris too.

I don't know what it is.

EDIT:
Looks similar to a persimilis too, a predatory mite...

But I don't know.
I also thought it could be the predatory mite. Maybe they are and the plant damage is something else.

Also, no spots that I can visibly notice to indicate spider mites. I literally took this by putting my phone up to the microscope. Not sure I could get a good enough photo.

If you're not sure, I'd hit it with some miticide and have peace of mind. Then buy predators to keep your plants clean as the miticide wears off. Id do that before bloom though.
 
Is it a white, almost kinda translucent mite?

You said you bought soil recently. cucumeris mites are soil dwellers and feed on thrip larvae. People will typically add them to soil and they last forever in there basically. You have specs of brown and white? could be somewhat severe thirp damage? If that is the case then cucumeris mites would be thriving and plainly visible on the plant as they hunt for the thrip larvae.

they are very cheap and thus quite commonly added to soil. Ill attach a pic below.
