If you do too much equalization or overcharging the plates can shed lead or dislodge sulfated crystals from plates.

Worse effect is too much charge current causing plates to shed lead.  Electrolyte appears it has fine graphite powder floating around. 

Lead sulfate crystals look more like rusty mud mixed in with electrolyte.  It should eventually clear dropping to bottom of battery.

My Interstate cells do the same thing, leaving what looks like graphite deposits on the bottom of the caps.

I always have grey deposit on the caps, but clear electrolyte.
