I'm using an Aspire with a iStick 30w. I have a 1.8 ohms bvc coil that i have to constantly replace. I just replaced one a few hours ago and my reader is displaying that the ohms have already increased to 2.2 in just that short amount of time. I have my settings on 4.2 volts(8.4 W), but sometimes turn it up to 4.5v(9.6W) as an attempt to counter the increasing ohms. My liquid doesn't seem to be too thick compared to all of the other juices i have tried. Does anyone have an idea what the problem may be?
