+1. Doesn't look burnt to me either and, if that's cotton, it's probably a bit too full in the coil, although the tails look ok. My suggestion is don't worry about it. If it starts to taste bad pull the wick, dry burn the coils, wash and dry the tank parts, re-wick and keep on vaping. You may wish to experiment with a build or two using a rayon wick. I find it less susceptible, if not entirely immune, to discoloration and burning, as well as being harder to choke in the coil (rayon shrinks when wet, vice cotton which swells.) I also believe it lasts longer and wicks and tastes better than cotton. I find it has a noticeable taste when brand new (others disagree), but this taste disappears after "break in," about a ml of juice or so, and thereafter is the best tasting wick I have yet tried. YMMV, you make the call. But I think you'll like it if you try.
