If it's not burning it shouldn't be an issue. There might be a bit too much liquid on the coil, but if it's not burning or getting in your mouth there shouldn't be an issue. I get that sometimes with my Halo Triton
tank. I wouldn't worry about it unless it becomes an issue (burnt taste, particles in mouth). If that does happen, it could be an amount getting to your coil issue or a heat issue. In the first case, use more on your wick so it allows less into the coil area (more mm of wick), or VV down a bit. If it's just too hot tasting for you, you need to increase the resistance on your coil or down the voltage on your VV a bit.
