Just curious why this happens? You come up with a really good recipe using (in my case) a Protank2 mixed at 12mg nic and 30pg/70vg at 4V. Then lower the nic to 3mg and use a sub Ohm device at .5 ohms and 20w and change nothing else but it taste terrible. This has happened to me several times and I don't understand why or if there is something I can do to make it work. And then some recipe's seem to work great in any device just to add to the confusion. Any ideals as to why this happens? Thanks!
