CSBuffered Vitamin C

When I opened my 3/4 empty jar of buffered vitamin C (first time after being gone for a month), there were brown tiny beads all over it, whereas it's supposed to be pure white powder. I doesn't appear to be bugs, but does anyone know what happened here?

It's the doggone humidity! When I opened my 3/4 empty jar of buffered vitamin C (first time after being gone for a month), there were brown tiny beads all over it, whereas it's supposed to be pure white powder. I doesn't appear to be bugs, but does anyone know what happened here?
