pg/vg

This is like getting blood from a Stoner

OK so I've not heard of bad vg or pg affecting flavour maybe vape some neat vg or just pg/vg and see if it tastes dodgy. At a guess more likely the nic or flavours are the issue.
ok thanks will try that
Maybe some of our mixing gurus can help you more.

@krang has the right idea, vape some 100% vg, if that's fine add the pg to make it to your normal ratio vape that, then add the nic and vape that. After all that you should have worked out what is causing the issue, if that's all fine and it turns out to be the concentrate post up the recipes that you using.
