been vaping for a week or 2, figured out how to by myself with try/fail lol. i noticed that now, however, that a week and a day after i got it, it feels like there's air very cold air coming into my mouth, like with no flavor or warming like the vape. i took it apart and looked at the holes on the side, they're both unclogged though one blows air and one doesnt.... is this normal or should i take this back to the place for them to look at??? thanks!
