Hi! I'd like to ask if this is normal? I mostly chain vape anf I get it in all my tanks after some use.

Is there any way to prevent this from happening? Do I have to change my cotton or my build? Hope you guys can help me out.

Yes that is normal.

It's streaking from the cotton in your coil. It has burnt, as well as maybe some of the juice. Changing the coil/wicking will fix it for a little while.

Yes, I agree. Your wicks are dirty. If you can't access the deck without draining, just vape it to empty first.

Yup after that possibly try lower power to prevent that. Are you getting any dry hits?

Thank you for your replies! Im not getting any dry hits at all. To be honest, the flavor is excellent and vapor production is good too.

The thing is if I lower the power, the vape becomes sort of anemic. I only had this sort of problem since I switched my everyday vape to this juice.

Is my temp setting too high at 350f? Or my power too high at 28w?

See the juice in the bottom of the tank, how dark it is? The juice in the bottle (on the right) is the same juice. All of mine do this as the get low, then if I add fresh juice, it gets a bit of a swirl look to it. This was a new wick, too. But definitely happens when the wick needs changing.

It happens every 3 days though, is that normal? Or does it depend on the formulation of the juice used?

I don't believe it is cotton burning. I did an experiment rewicking a used coil filling with juice and let it sit for a week. then started using it and within hours had the same thing. I believe it is the coil oxidizing.

Its the juice...
Some sweeteners have a tendency to caramelize when heated and some juices will oxidize your coils faster than others.
Like others have said though,nothing to worry about. Just keep an eye on it and change your coils/wick accordingly.

Those are pretty mild settings really. As bondo said, it is probably the juice. most the juice I vape is completely clear and I don't get that happening in my tanks unless there is a problem, like burned wick, really dirty coils, etc...
