Also another thing if I make some semi awful juice I try mixing it up with 50percent base. Pg and vg mix and it fixed alot of my earlier nightmare DIY juices. I can tell you to keep going because unless I use that friggen blueberry by capella there hasn't been anything unvapeable in a very long time. Might not all be top notch, but my worst is normally better than what I can find commercially now.
I think it may be one flavor I used in some of the recipes that don't agree with my pallet. I shall be seeking and casting it out... I am suspecting the Pear or Honeydew maybe from this recipe maybe.
