Welcome and glad you joined.Howdy, I'm quite new to vaping and could use some direction.
I have enclosed some information which may help you answer your question. Just a side note, sometimes a flavor like toffee can be elusive/tasteless no matter what setting you use. Some folks can taste toffee and some folks can't , no matter what they vape it in, mix it with, or who's brand etc.etc.. Might want to try/vape a known (tasted on another atty) good tasting flavor mix on you new equipment.
