I've been told by multiple people that "It's fine to leave your resin in the vat till the next print," even suggesting that months at a time is fine. Well hadn't found time recently and let my leftover resin sit for a bit. What would this dark film on top and white residue on the bottom be? The dark material mixed in fine, but the white residue seemed a bit more solid or at least resisted any movement from the stirrer.

I keep my printer closed and in its enclosure in the garage so no light would be getting in. I'm using elegoo's abs like gray resin.
