You normally get 18% percent nic joose, but when you add flavors or PG/VG you will be diluting down the 18% nic that you bought to a lower lever. Probably should have just left that off your order.
If you get 50/50 nic, adding flavorings will be altering that mix (most flavors are 100%pg - the actual flavor)
Best to get IMHO 100mg nic in 100% VG and use a calc to get your PG from flavors and a little bit you add to bring it to what PG/VG mix you want.
Since you've done some studying I'll assume your aware of safety precautions etc....
Im in Mesa, if you need any help let me know.
