I've had my bloog kit for a couple weeks now and love it, but the last couple days I've noticed a weird taste when vaping off the pass thru, even on new cartos. I can't begin to explain what the taste is, but it masks the taste of the cart completely on inhale, and makes me want to throw up. it's not a burning taste, it's just . . . disgusting. I can't explain. I switch the carto to a battery and it tastes fine. any ideas of what's going on????
