Hay all just wondering if anyone else has has this happen. I have been vaping a few months now and I am very happy with the v4l juices but I've noticing with my gunslinger and my outlaw apple in my ce2 carts after a day or so of vaping the juices get darker almost black and have less flavor and alittle burnt taste to them. Just wondering what the problem might be. I think it might be the carts coil burning the juice or the juice is somehow separating or I got a bad batch of juice. I have bandit berry and peacemaker peppermint and have no problems with them. please help
