Just got my zen today wrapped my first coil and its going pretty good

Slight metallic taste but I am "Just
vaping it" till it goes away
How long does it take to get the wick to properly wick?
seems like mine is a little slow at it so I am vaping at 3 o'clock for now.
I now see why people say they have to lower there juice's nic. .... I am vaping 12mg so I will try and just deal with it
Welcome, brother maleko! ;p
Since expert advice is lagging, I can try some inexpert advice right now.
The "just vape it" really only works for a new Zenesis with a Zen-made wick/coil. I guess. You shouldn't get frank metallic taste. You shouldn't get any metallic taste after, say, quarter of a tank, provided that you seasoned the coil a bit (glow - quench in PG - pulse fire - quench - repeat). I guess you do have a dreaded hotspot.
To test that theory, take the cap off, and slowly tilt the PV to 4 o'clock or until you can see there is liquid on the wick. Then go back to 3 o'clock and fire away. See if anything glows. Nothing should glow, and vapor should come out a plenty.
If something glows, then try to pulse fire it vertically and see how it starts glowing - should start glowing from the top, then the whole thing relatively uniformly. If there's any portion that's outstanding, you need to do the nasty, i.e. fiddle with it. Very, very gently nudge it around. At first do that without firing, but as you get the motion you can actually do it as it glows to see the results in real time.
