first of all ive been vaping about 8 months. Recently started using cartos. I like vg juice. My question is.....i fill a carto with my vg juice. when I vape I vape rather heavy. It seems that the vg juice doesn't wick fast enough and my carto seems to go dry quickly (way before I would assume 20 drops should last). Has anyone noticed the same thing? Did you fix it? Our did you switch to a pg/vg mix? Or all pg? Its driving me nuts. Btw I'm using lr cartos and I know they will burn up juice faster. On a 510 hello 16 after the damn tsa took my silver bullet out of my luggage (that's another story). Thanks in advance.
