I've been building rdas for a while, I had a rta but I never really liked it. I never could sell so I figured I'd give another try. I've been vaping today but the weirdest thing is happening. It won't wick unless I unscrew the top of it and let some air in it. I remembered reading something about vapor lock, but I had never experienced it, obviously because I use rdas only. So is this vapor lock, or do I just have a little bit to much cotton? It's the mikes vapes blaze rta. This has never happened before. Usually if I've gotten to little cotton it floods and if I've got to much it still wicks, just to slow to keep up. I noticed I didn't see any bubbles and I usually do. As so soon as I open top cap a couple giant bubble coming up from the bottom and it's wicked again lol
