I have juice that has gone brown in the bottle so it's not always a gunky coil, put it down to chemical reactions like others have said
That's the nicotine oxidising and changing colour, it's quite normal.
I see that makes sense. Here’s another pic doesn’t look too good to me but I need to know these things to prevent me wasting money if I don’t need to
Trust me, this is not bad. Seen some nasty crappy coils just covered in what could only be described as black tar, and people kept using it [emoji23] it's unavoidable. Any sweeteners and colouring can result in gunk, as well as to high/low power. With too high power you're burning the wicks, since it doesn't have enough wicking capacity. With too low power, you're pretty much cooking the liquid instead of vaporising, and any sweetener and/or colouring caramelises on the coil. As I say, it's unavoidable. As long as it tastes good and don't look disgusting it's pretty safe.
Yeahhh... no, at this point when it tastes like burnt rag, it's time to replace. If they all do it around the same time, means it's just the nature of the coils. You tried different ones? I know there is one that lasts longer than others, but which one? Not a clue. Ask around, you'll definitely find someone on the forum that can help.Cheers for the info man, why has it started to taste weird then? It’s not a burnt taste, just a strange taste now and not the most pleasant, especially the after taste. I’ve only had 250 puffs on this coil. It seems to be happening on all of them around the 300 hundred mark. It’s a falcon 2 sector mesh
