Hello all, I've been vaping for just over a month now. I quit smoking completely and love to vape. However, I've noticed that I am getting a burnt taste when I vape sometimes now. My current setup is a sigelei zmax v5 and a kanger protank 2 and the kanger air control valve. I've already changed the coils (1.8ohm) a few times but I still get the burnt taste sometimes. Can anyone shed some insight into this?
