So I'm new to vaping and yesterday I bought a PV D2 and SMOK TFV4 mini. The guy at the vape store set it up for me and now it's barely making any vapor. Im at 60watts with 90pg juice. What could i possibly be doing wrong? I get very little vapor and I know i should be getting massive clouds. Any response would be appreciated, just know that I'm new to vaping and it seems like a different language to me. I had a itaste v4 and that was making more vapor than this.
