It's a possibility. But in 10 days I haven't had this issue.. with the same wick material.
That's why I re-wicked. And I let it soak for a good long time.. In the 2nd blueberry mixture. hah. Doesn't look singed.. I suppose it's possible though.
So far, still no coughing with a non-blueberry mixture. I could even crank the voltage up a bit after switching.
I'd pick my blueberries from a different bush then.... Just saying...
