[Question] Burning Out Coils

Hey all-- I'm currently smoking on the horizon V8 and every time I replace the coils, I seem to start getting a burnt taste within three or four days of vaping on the low end of the 'Best' wattage range. It happens even faster when I use sweeter juices.

I'm still relatively new to vaping, so maybe this is common. Anyone have tips on what %mix juices or coil types this would happen less frequently for?
