Caramelized flavorings on the coil leeching into the juice is what it sounds like. I have a fruity tobacco juice that does that after a day or so. Nothing to worry about.

This and the chamber becomes hot and bakes the juice in the tank. Aromamizer and Billow address this problem.

I am using Aspire Nautilus and changed the coil two days ago, and also washed the whole thing yesterday. However, I filled the tank with clear juice this morning and now the liquid that is left in at the bottom is all brown - WHY?

Thanks!!!

It is the heat oxidizing the nicotine ...............

yes its oxidization,that's all...

Happened to me all the time, especially on sweetish flavors...

I too was using a mini nautilus

Like others have said,its nothing to worry about...Sometimes it makes the juice even better tasting/stronger ;)

I wouldnt let that particular juice hang around too long though, try to vape it in the next day or two at the latest , after ahwile it can start tasting nasty (usually first its better then.....gets a bit nasty....depends on the juice though...)

What juice are you using? Most of my flavored juices will darken as I vape toward the end of the tank, or if I am out in sunlight. I attribute darkening of my flavored juice to heat carmelization of the flavorings and backflow. But I'm vaping a nautilus mini with clear unflavored 18 mg Nic base and it's as clear when the tank gets low as it was when I first put it in so its not the heat causing Nic oxidation that causes the darkening. If you are out in the sun it will cause Nic juice to darken.

As BunnyKiller said, the wick does work both ways. Caramelization gets on the wick from the coil. As fresh liquid gets pulled into the coil, some of the caramels get pushed back. That push back is slower so it takes quite a while before you notice.

The longer you keep using the same wick (multiple tanks worth) the darker the caramelization. I'm a high ohm low voltage vaper. I think it is a slower process for me. I go about two weeks before it gets to that darkened point that I know it's time to re-wick.

What you are vaping has a role in the whole thing too. Sweeter vapes caramelize faster than less sweetened etc.

Good advice above. Also, vape the tank as dry as possible without burning the wick. Remove the coil and rinse the tank and base every couple of tanks or so, and wipe the outside of the coil off. The effect is cumulative if you keep topping off the brown juice. It will eventually get to the point where the juice goes brown before you vape half a tank if you don't clean it periodically.

My new vanilla juice turns dark brown really quickly and that's without the coil or wick being 'gunked.'. Basically liquids with sweeter flavourings both turn darker quickly and gunk coils faster so the natural sweetness makes them dark plus the gunking of the coils tainting the liquid.

I only buy clear liquids. I have really sweet bakery type liquids like 13th floor elevapor 'Django,' Suicide Bunny, Space Jam. max VG stuff from G2 etc but it is clear to begin with and for some reason stays clear maybe as it's high VG...?

I have cheaper B&M liquids (rebranded Hangsen) where the sweet ones do go darker, but premium sweet ones seem to not go darker.

Weird. Or is it? Must be a reason why the cheap sweet ones go dark but the expensive sweet ones do not...

Again, the juice in the tank is getting super heated by the exterior of the coil chamber. That's your main culprit. Gunked wick back flow adds to it. The Aromamizer solves 80% of the problem.
