I've got several of the clear pucks that ccom sells - (Round Crystal Humidifier – Clear)

They contain clear gel balls that swell up when you add distilled water. I have noticed that the gel balls in one of them has turned a darker color. Kind of a gray or charcoal tint. There are no obvious fuzzy or dark spots or pieces in the puck other than the gel balls. There's just the darker tint to the gel balls.
You think this is mold?
Anybody had these gel balls just simply turn gray on you?
I've had no direct experience with mold and wondered if I should just toss this one puck just to be safe.
