Stumped, pests?

[Chironius]

Hi, was wondering if anyone has ever seen anything like this before? Decided to look at some week old seedlings under microscope and saw this on all seedlings, didn’t see any bugs anywhere just this on top of leaves, thanks!

It's hard to tell for sure they look like mite eggs. You should find adult mites if there are eggs.

Don’t see any adult mites anywhere or any traces and this is the top side of leaves, thought eggs would be on underside.

No mites can go anywhere. They just prefer the underside most. What looks odd is I can see what looks like an embryo in the center?. . If you're not finding any adult pests they could be tric heads no stalk. Most plants will have that on the surface of leaves.

They are unicellular trichomes.
designed to protect the seedling from high temps and vapour loss.
nothing to do with pests
