Hi everyone, I've been vaping a little over 5 years now and making my own juice for about 4 years. In the beginning, I used flavors, but I like to keep it simple now. I was vaping a cheap pen-style battery (ego/510) and making 50/50 juice with 12 mg nicotine and using a 1.8 coil. That seemed to be a good nicotine amount, as I had started with 24 mg and have gradually cut down. Now, I just got a Smok Nord and the coil is 1.4, but I started getting palpitations and got a little light headed when I started vaping it. I am under the impression that certain coil strengths mean you need to cut down the nicotine? They put a .6 coil in the kit also, and that means I need to use less nicotine for that coil, right? I'm so confused about the nicotine and coil strength, and pointing me in the right direction would be most appreciated. Also, if I use the .6 coil, whats a good pg/vg ratio? That needs to change too, right?
