I am using a Triton by aspire on an SMY 60 running at 45 watts. My normal mix is 30/70 pg/vg 3nic. With most ejuice I can vape without any TH. For some reason when I vape on a shop custom flavor there is this horrid TH. The flavor is great it tastes like a handful of skittles. Not sure what's going on, any advice?
