If you are able to balance a checkbook, you know enough arithmetic to do this. You just take an average because, when the liquids slosh together, that's what happens.
For example, if you buy 36mg liquid and you want to vape it at 6mg, you will use 1 part of the nicotine for every 5 parts of no-nic liquids (pg, vg, flavoring, distilled water, liquid sucralose...) so the nicotine used will be:
36 + 0 + 0 + 0 + 0 + 0
The average is 36mg divided by 6 parts which is 6mg.
Similarly, if you nicotine is in a VG base and all the other stuff you add is PG, the formula is:
100 (% VG) + 0 + 0 + 0 + 0 + 0
So 100/6 means your liquid will be 16.6% VG. (So you might want to include some more VG.
In my pre-deejStuff days, I vaped Tasty Vapor and I worked up a ton of the ratios for mixing doublers. I'll see if I can find it. If so, I'll put it in my google pages and post a link.
When it comes to mixing the flavors, I can't help you at all (unless your aim is to make stuff so foul you quit vaping forever.)
