juice gets darke

[fairweasel2323]

Just wandering I notice in my Kanger T4s mostly maybe cause of size but the last bit of juice in clearo is always way darker sometimes I empty it out, others I just add fresh to it... using T4 on a Ego 650mah battery...is this normal?? It did it on my 510 batteries too

Coil might be dirty, or it could just be the juice "cooking"

Nicotine over time darkens juice.

yeah come to think of it when it gets darker usually when I know its time to clean and ill run hot water through theses T4s and then Dry burn but usually they stopped hitting good too, probably just the weaker 510 battery's, now using a Ego. I noticed when I dry burned with the Ego it burnt way more crud off then the 510 battery had power to do
