Limitless Plus RDTA - Black wick problem

[caffeine93]

Hi everyone,

So I've been having this problem since I've purchased the Limitless Plus RDTA. Once I build the coils and put the wick inside of them and vape, the vapor seems to be alright and the wicks are clear for like 2-3 days. After that, wicks progressively start getting darker (sometimes it starts from one side of the each wick, sometimes from both) until the point when they get completely black (take a look at the pictures), also..when I wipe off the inner walls of the chimney, the paper has the same black/dark brown "vapor" condensate on it. The liquid I use is 80% VG, it's yellow in color (lemon flavor). The coils have a diameter of 3mm, total resistance of the dual coil build is ~0.7Ohm and power 50.0W.

Any ideas?

I use very sweet, very high flavor percentages and get basically the same result.
Since I vape about 45ml per day I change my wicking every three days.
In my case the black/charring/gunk is caramelization of the sweetener and flavor however it doesn't change the taste of my juice.

Mine does the same when vaping sweeter juices. I change mine when the taste becomes affected, more like a slight muted/burnt taste.

All completely normal.
