aspire nautilus mini vapor production problem

[divyabhatia]

Hi guys my current setup is a vv battery, aspire nautilus mini 1.8ohms coil and vaping 70 30 pg vg hangsen caramel flavor e liquid.I primed my first coil by putting in a drop of e liquid in the coils center hole and one drop in each of the four small holes of the coil then I waited 10 mins before vaping on it and I got fantastic clouds /plumes of vapor from my first coil .For the second coil I just filled the tank,screwed in a new coil and allowed the juice to soak into the coil ,I got way less vapor production this way , and I've been getting less vapor since.any suggestions?my wife does not know how to smoke or vape , I gave her the tank to take a pull when it was new with the first coil and I think she blew air into it instead of taking a pull the tank has been performing poorly since.Does priming the coil make such a huge difference in performance or was it due to my wife wife's mistake that i'm not getting vapor now even with my 2nd and 3rd coils?
