hi guys, been noticing everytime i wrap my coils 24 26 28 awg 2,2.5,3mm to 0.5ohm and install into my subtank rba and start vaping at around 16-20w, after like half a day the wire coil turns black, and i mean black not brown.. i understand that sweet juice will tends to gunk up the coil and make it turn brownish but mine is black.. wondering is it normal or am i doing something wrong? thanks
