I recieved my 3.5ml tank today(my first tank) and placed some drops in the cartomizer and then filled the tank around it. I then put my finger on the bottom of the cartomizer and inhaled to wet the poly inside. The poly was damp and slightly tan. As I smoke it I take off the drip tip and I now see that the top of the poly is pretty dry and completely white. I am not familair at all with tanks, but isnt the entire poly supposed to stay wet and and slightly tan like when I first filled it up? I think my VP is still working fine I'm not getting a burning taste or anything, but I am totally new to vaping so I'm not really sure about any of this haha.
