just received my new set up on Tuesday. The istick 30 and nautilus. So the nautilus came with a 1.6 coil and I've been vaping around 7 watts at the second largest air hole. I'm not filling it up to 5mls..only to around 3 because I like to change flavors. For some reason, everything seems hooked up tight, it will be ok and then all of the sudden it's leaking down the battery and out the air holes. I take it apart, let it drain, wipe it out....it's good for a while and then the same thing happens again. I don't know what I'm doing wrong, but I'm frustrated. Any tips or tricks? Or common mistakes? Thanks!
