Hi all, I have the Kanger Topbox kit and am currently using the mini RBA that came with the kit as my coil. The guys at my local vape shop built it for me (ahead of the FDA regulations going into effect - I made sure of this so I could see how to do it in person at least once and ask any questions I had) and they seem to be very good at building coils so I assume they're doing it right. The other day, I cleaned my tank and refilled with a new juice flavor - caramel macchiato, if that matters at all. The juice appeared to be clear in color in the bottle and when I first put it in the tank. Now, the juice near the bottom of the tank has sort of an amber or golden brown hue. The juice near the top of the tank is still clear. When I tilt the tank, the amber color tilts too. I opened the RBA, and the cotton in the coil is still wet and is dark pink in color. Does the cotton need to be changed? Or is something funky with my juice? I only vaped using the RBA with the cotton they put in for me for for a day or two, and most of it was with the previous juice flavor (Circus Cookie, possibly my new favorite). However, I did vape quite a bit that one day I did use the RBA. I haven't been vaping since I discovered this issue as I wasn't sure if it was safe. Any advice for why my juice appears to be two different colors would be greatly appreciated.
