Why do salt flakes start building up in a bottle of mineral water after it was first opened?
I noticed that mineral water with high mineralization doesn't have salt flakes floating on the bottom of the bottle on store shelves, but when I open one, after some time they start accumulating. Does it have something to do with decarbonation?

Mineral water is produced artificially by adding salts to distilled water or aerating it with carbon dioxide. The mineral content of both natural and artificial mineral water varies greatly, and in some cases it may be less than that of ordinary tap water.The Truth About Himalayan Sea Salt | Joe Rogan

Answer 2
It could be gases (oxygen or carbon dioxide) from the air, competing as solvents with the salts. I know the reverse effect: adding salt tends to drive out gases.
I'm not sure whether this gas explanation is more significant than the pressure explanation. But, you could do an experiment: briefly let the pressure out and then retighten the cap without letting fresh air enter, and see if the crystals still form.
