Hi guys, I've been having this weird problem of late. Im using a Smok TFV4 on a RX200s and lately the vapor has been leaving black/brown discoloration on my teeth. Its nothing permanent and can be brushed off easily, but it is embarrassing.
It only happens with one specific brand of juice, as I've tried it with different coils and tanks and it still happens. I dont think its a burnt/used coil problem as there is no taste difference, however it does admittedly only happen after a day of coil use. (I use the coil for much longer with other juices). I run the coil at 70w, which is within its spec'd wattage (TF-Q4, 40-140w)
Is it the juice, or am I doing something wrong?
