This is my first post so hello everyone. I am excited to join the forum. Just bought a Smok Alien TC 220w with "the cloud beast TFV8" as a tank. I have loved every minute of it. (I will post pictures). I am smoking 3mg nicotine in my liquid. I currently have it on about 80 watts not only to conserve my liquid and my battery, but because when I go over 100, I seem to get a iron taste in my mouth very similar to the taste of blood. Could it be my liquid? Am I doing something wrong? My tank says it's rated 50-260 but it says it's best 120-180. I'm just seeing if anyone could recommend any setting changes? Thanks so much.
