so I'm new to the vaping world and I got my kanger subox mini in the mail yesterday and everything worked perfectly up until tonight when I started getting a burnt taste. I was using the .5 occ and for some reason I can not get the burnt taste to go away. I switched to the rba and the taste went away but came back very quickly so I cranked my wattage down to 18 with the same problem, and I went even lower when I switched to the 1.5 still with the same burnt taste. I soaked all my stuff and everything. I used a 50/50 blend as well as an 80/20 vg/pg blend at the beginning, both tasting great but now both taste burnt. I don't know what I'm doing wrong, help!!!!
