I'm having trouble figuring out why my flavor would be diluted if I add the nic later. For example: I mix a 30 ml bottle of my favorite recipe. I use 3% PG based nic (0.9 mls). I add everything but the 0.9 mls of nic, which I'll add right before vaping. You mean to tell me I'll be diluting the flavor with that? I just don't see it. I'm only adding a portion of the recipe already calculated to be added.
It wouldn’t, if you do it like that. I do the opposite, I make the nic base allowing for flavor to be added later. I just note what percentage of flavors to add.
