Had this OMG for a few months and very happy. I recently got a 4mg Strawberry Apple Kiwi (aka The .....!) juice for my tank. Got a new dual coil in it and ive been noticed that the vapor production is less thick, etc. The throat hit is stronger than a 8mg but I don't think the coil is burnt. Its a 1.5 resistance and doesnt make bubbly noises like my others. I tried out my other tank with a different juice (same coil resistance) and that had more vapor. This is on a fully charged battery. What could be the problem with my new juice setup? Is it the coil or battery that may be bad? Or is it that nicotine makes less vapor production?
