Sorry if this has already been asked before but I dont remember seeing anything on it. My brain is not wanting to fully function so having a hard time working this out which means its really simple lol. I have a few flavors that I love so I want to get some premade flavoring batches made up. I will use one recipe as an example. It uses a total of 12% flavoring using 7 flavors. I am wanting to premake the flavor mix so when I or a friend would like some all I would need to do is make the base with the appropiate nic and then add 12% of the premade. My issue is how do I figure out how much to mix to make the base? I normally use ejuicemeup. Would I just input like I was make a enourmous bottle of juice (whatever the end result would be with my premade if I made it all into ejuice) and mix from that or is there a different formula i should use or a program to help me figure it all out. I know kinda a stupid question and I am sure the answer is super easy but my brain is not wanting to function right atm so figured I would hit ya'll up see if you could help me out
