Anyone know what would cause a line of flavors I got to have a base flavor kind of like buttered popcorn? I can taste the predominant flavors as well, but six of the seven different flavors kind of have a funny taste lying underneath. 18mg nic 85% pg /15% vg. Better th than my goto vendors e-liq. @ 18mg nic. I know Lorann or Flavor Art sell a th addative. Could that be the culprit?
