does this look like the work of spidermites?

this is bad there all over this pre 98 bubba but not on the other plants its in diffrent soil than the others

That third pic sort of tripped me out, the other two seems like just a watering issue thought not hat classic spoty brittle yellow mite spots.

i cant really tell with the definition of your camera. look on the underside of the leaves and with a magnified glass or jewelers loop you should be able to see for certain if they are spider mites. if so hit it with some neem oil.
