The young persimmon trees decline might be due to very small mites

Update on April 29, 2021 

The digital microscope came on April 29, here is one of the videos from today.  The mites are very small and rectangular.  A few of them here:

I lost a number of young persimmons last year.  This year I am watching them very closely.  A  young Texas persimmon tree just started to bloom, and I could see some fine webs on the leaves.  After shaking the leaves on a white paper I found a few thrips, an aphid, but could not see any mites.  It took me a good hour and a real camera with a zoom to get a dissent portrait of just one mite.  There are many of them, but I would need a camera stand and maybe a microscope to get better pictures.  I do not know the species name, but hopefully someone can ID these.
