@olafwobbly Hi and welcome. Regretfully I'm not expert with your tank, but it looks like you may have too much cotton there? I did a quick Youtube search and here's a tutorial video. Skip to 12:00 for cotton instructions. The reviewer also goes into detail that it is easy to get dry hits if the tank is not wicked properly. Hope it helps.

It's not burnt. It's the juice discoloring the cotton in the choke point of the coil (where the cotton enters the coil is a slight choke point where the discoloration occurs).

Yea its definitely not burnt...its just your juice discoloring from the heat, but you definitely appear to have to much cotton in there, esp for a tank atty. if you cant set your mod on the table and pull the ends of the cotton through the coil freely without having to hold your mod down to prevent it from falling over you have a bit too much cotton, also i would trim your tail ends back a bit to thin them out, it seems your clogging your airflow a bit. Once you have your tails down into the juice holes below your deck only leave enough poof as wide as your coil because once the cotton is saturated it will expand. I would be surprised if your not getting some spit back.

+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.

thanks for all the help!
but i thought that for scottish roll wick it need to be tight?
i guess i have to practise more for wicking.

but does it happen to coloured juices only?



attached the video for scottish wicking.

I get this all the time when I vape dark/ very sweet juice.. It is definitely the juice that does it, I burn off the coil re wic ( every night I use that juice) an put in a different juice that's clear and the same coil/wick last me for days and days.

He is also using an Rda which makes holding juice a necessity. The cotton in an Rda is essentially your tank. Your using a tank so you dont need that tight of a wick running through your coils because your main focus is drawing juice through the wick to the coil... the tighter the wick in the coil the harder the wick has doing its job effectively.
