I keep getting dry hits on my mini, I have a 1.8 ohm build, 28g 2mm 9 wraps I think. I do my wick like they show on the videos just enough to pull thru the coil and it be a little tight then put the tank on pulling cotton up and cutting it just above the edge of the coil tank(whatever it's called). Using Japanese cotton. My juice is 50/50. Please help. I am dripping to wet the wick before filling my tank.
