Yeah thats probably it. Just getting dry hits alot with 85VG... That's ment for drippers, some sub ohm and RTA's can't even handle that thick of
juice. You'll lose flavour at higher VG too. VG = Clouds, PG is thoat hit and holds flavour better. 50/50 tastes better then 30/70 but 30/70 is smooth and makes nice clouds.
