I'm using a Kanger T2, and sometimes I'm using the ego-c cartrige tanks, and I'm using an ego-c 600mah battery.
After I vape for a while, I notice that the juice gets really dark. Is this indicative of something? Or is it perfectly normal? I'm just worried that this means that the voltage on my battery is too high. The juice that I'm using is a light amber/gold color in the bottle. But after I vape it for a while, it turns a dark brown.
Is this normal or am I doing something wrong?
