Taste Burn In All Eliquid

[Lucas Rong]

I would always taste "burnt" when I exhale through my nostrils. Now I didn't have this sensation before. It just became noticeable to me about 4 months ago and I have been vaping for over a year now. However when I try to exhale as much as I can from my mouth, I do taste house the eliquid is suppose to taste like. However, when combining both nose and mouth I got this really undesirable burnt taste for all eliquid. And I know it is not the burnt wick/melted insulator because it is an rda with peek insulator. Anyone experiencing this issue?Any remedies? Thanks everyone.
