Black sludge coming out of my coil

About 3 weeks ago I got an Aspire Mini Nautilus. After a couple days black sludge starts pouring out of the holes on the coil. It turns my liquid black, tastes bad and then it's like it's stopped up. I've gone through several coils and they all do the same thing. Is that normal?

What flavor juice?
What PG/VG ratio?
What nicotine lever Mg/Ml?
What wattage battery are you running?

Isn't the snickerdoodle a dark liquid to start with? Dark liquids can clog/burn your coils faster than clear liquids.
PG/VG Propylene Glycol/ Vegetable Glycerin are the two main liquids in vape juice. I use a 50/50 ratio in my Nautilus. People that drip/chase clouds use a high % of VG because it makes lots of vapor. It's thicker and when used in a tank can have problems going thru the wick and clog up the vape chamber. your local vape shop may sell both ratios, so be sure to let them know you are using a Nautilus tank and want 50/50
I run my Nautilus at 7 to 8 watts.

What @RMarcusY said - darker and/or sweeter liquids tend to gunk up coils quicker. The number of days you've had your coil doesn't matter so much as how much juice you're running through it - I've had some juices that gunked last-generation coils like those for the Nautilus in as few as 3-4 tanks, though I could usually get a dozen or more.

If you're really liking the gunky juice and the cost of coils is getting to you, you might want to look into either rebuilding your stock coils or getting a device that's meant to be rebuilt - either choice will require some more work, but will dramatically drive the price down. Failing that, look for lighter juices that aren't as heavy on the sweeteners - and as mentioned above, you probably don't want to go above 40/60, maybe 30/70 if you don't chain vape, on the PG/VG ratio for the tank you're using, as thicker juices tend to wick slower and with the little wicks on those replaceable clearomizer heads you run the risk of getting burnt, dry hits. Your bottle may have the PG/VG contents labeled, if not ask your shop next time you're in - if their staff is good for anything they should be able to tell you.

Liquid is snickerdoodle from great vapes
I don't know what PG/VG is
Nicotine 24mg
Tesla battery I keep it on 10
I've only had that problem when I used a chocolate juice. I've run 16-20W on clear, high VG juices, and I don't get that funny taste/colour. You just have to remember to keep the coil primed up. you can do that by blocking the hole on the side and sucking to create a stronger vacuum inside your tank, and should help more juice get to the coil. The newer generation of BVCs from Aspire have holes that are a lot larger than they used to be as well.
 
Thank you all so much. I took it back to the store I got it from yesterday. They said it was probably the sugar in the snickerdoodle. They took it apart and cleaned it, gave me a new coil and a free bottle of liquid. I got a clear one this time that's not as sweet. So far there's no sludge. Again thank you. I've learned alot in the last few days. I've been vaping for about a year. I didn't completely stop cigarettes until 6 months ago. I had a basic Kangertech setup until about 3 weeks ago. I upgraded to the Tesla.

Stick around here for a while and you will meet some great people and learn about huge savings on eliquids and hardware.
You can also find links to reviews on different eliquid and accessories.
This hobby is SO MUCH more fun that smoking.
It also will help you live longer;)
