So I got this juice from 5 Pawns a few weeks ago and have been vaping it off and on. Lately whenver I vape it I get weird hits that don't produce alot of vapor. Tastes fine and i'm loving its flavor just not getting satisfying hits. All my other juices are fine and normal. I'm using an MVP with an Aerotank V2. 1.8 coil at a 8.5 watts usually. Any ideas what could cause this?
