I have an itaste vv v3.0 and a kanger protank 2. I've been building coils using organic cotton and 32 gauge kanthal wire for about a month now. But earlier I built a coil put organic cotton wick in it and it seemed to be fine. I put it in the base put the base on the tank and put it on the battery and the airways were blocked. So I thought just a fluke and built a different one. It did the same thing. What is going on? Any ideas?
