Ok, so I have a bunch of "base" made up that is 20 PG/ 80 VG and 6mg nic. I would like to add more vg as well as cut the mic level down a tad. So, if I mix say 10ml of the "base" and 10ml of 100% VG, what would my PG/VG ratio be? I know cut in half the mic will be 6, just trying to figure out the PG/VG ration. Thanks!
