i had gotten a crown tank maybe about a two months ago. This past week I bought a new eliquid by beard that is a salted caramel, which I really like. It is 70/30 which is the same ratio as most of the juice I vape. Whenever I try to vape it it seems to burn my coil within 1-2 days???? I always prime the wick really well and let it sit for a good while. Start at a lower wattage and work up (was staring around 25w but after this happened twice decreased to starting at 10w)around I haven't found this to happen with any other juices. I use the 0.5 ohm coils on a fuchai 200w tc device had been using on an eleaf 100w. Any other advice? Or is it the juice? I will be bummed if it is the juice cause it is yummy for about a day until the coil is burnt to oblivion
