Ejuice is getting darker

[Bill K]

I'm having an issue with my ejuice getting dark. Its not tasting bad but I have no idea what I'm doing wrong! I am using gorilla vape coffee light and sweet with a mix of 60 pg and 40 VG at 3mg of nicotine.
I'm rebuilding my kanger subtank rba with 26 gauge kanthal wire (5 wraps) and Japanese organic cotton which comes out at .8 ohms. My subtank is used on a Sig 150w at 16.5 watts. What is causing my coils to turn my juice so dark? I just rebuilt the Atty a day ago! Your help is much appreciated.

2 reasons: Coffee and sweet. Darker liquids and sweet liquids will gunk up coils much faster than a clearer juice. Also, higher temps burn more juice quicker so you're going to accumulate more residue along with the bigger vapor. I wouldn't have thought that you could gunk a coil in a day unless you went through 20+ ml but if it's a really sweet liquid, it can happen.

Sugar (or sucrose) tends to burn easily. I'm surprised that it hasn't affected the flavor as you use it.

I vape a vanilla custard that turns my juice black and gunks up my coil pretty bad. The dark juice by the end of the day doesn't affect the flavor and having to dry burn my coil and re-wick it once a day is worth it to me since I really like this juice.

I have been rewicking once a day! Every time I dry burn my coil to clean off the gunk the ohms fluctuate so much that I land up making another coil.. What the heck is going on?
