Do they squish or explode LOL! Find a pic on google image and post it, that would be more helpful, a written description of a tiny white bug is very, not helpful at all fuck it could be anything. Try looking up fungus gnat or root aphid pictures and see if that matches what you found on your plant, then report back. Get a dope scope too, very helpful for identifying pests, especially when your trying to describe them in a written sentence!
