I also have been getting brown stains more than when I smoked..but mine are mostly on the inner side! and I also switched from coffee to roobois tea a few months back-
At the last cleaning, the dentist confirmed tannin in tea is a big culprit but even more so with sugar as it makes the stain stick even more!
So if PG or VG are sweeteners, then the combo of tea and vaping could definitly be a possibility for an increase in stains..
.. brushing teeth well with electric toothbrush right after the tea will help if you can remember to do it
