Ive been getting most of my liquids from TastyVapor (this past year) and go for 80%PG and 20%VG. Is this odd? For the most part this works for me but based on reading some threads Im wondering if this adds to any carto gunking issues or carto/tank leaking? Its not happening all the time which leads me to think its a bad carto vs the juice otherwise It would be a consistent issue...what PG/VG ratio do you prefer? I'd love some input!
