I have been experimenting with mixing my own liquids for a couple weeks now, and I seem to be having a difficult time with it. I use the calculator and mix everything exactly. I have used 12-20% flavoring, steeped for a week, or used the hot water method. But all of my liquids do not taste right at all. Notably, the dominant taste I am getting is from the nicotine pg. All of my juices have a very peppery taste to it. I am using TPA flavoring, and extreme vaping nic/pg/vg, mixing around 15-18mg. Am I missing something here?
