Just got in 3 bottles of new juice (dont really wanna say what vendor). 2 of them are great but the last one i tried had no vapor production at all. It smells great and even has throat hit but when i exhale there is barely anything. Tried it in a carto and also dripping and same result. I got some Walmart VG ... should i mix some in???? The mix is 80/20 pg/vg.
