I need some idea's. I have a super tank mini i wanted to use on my Pico with the 0.5 ohm coils. The past two weeks I have only been able to get minimal flavor at the best. I put on a old e leaf mello 2 tank and flavor is so much better. After changing coils, drinking water and thinking it was me, I was fed up and changed tanks this morning. Anyone have ideas whats wrong or i am doing wrong. I am using 70/30 juice and no visual leaks are present. Could it be air getting in somehow? Thanks for your help.
