Hi all, I have the Smok Cloud beast TVF4 tank and just bought the TF-T4 quadruple clapton coils. I primed the coil really well and also let it sit and soak in for a pretty long while. Oh and cleaned the tank beforehand. Started at very low wattages building my way up (mod is Joyetech Cuboid if it matters). Juice is 70/30. How come it tastes so horrible? I don't know how to describe it... Not a burnt taste, but metallic and weird. There is almost no vapor produced at all and the tank gets very hot. What am I doing wrong?
