Many possibilities, but the one that has occasionally hit me is too much
pressure when coating. Even with a soft brush, you are pushing bristles over
wet paper. Too much pressure on the brush and you (I) lift some of the paper
fibers up, they aren't coated well, and show as white specks.

Hope that helps.
