Looking for some advice on mixing this concoction. My son has a 200ml bottle of 50pg/50vg of no nic, and I have a 1liter bottle of 50pg/50vg 100%nic. He would like to be at a 24mg nic level.at 50pg/50vg We checked on ejuicemeup calculator and aren't sure of the measurements. The calculator says 48ml of nic ejuice and 76ml each of pg and vg. Being that the pg and vg is mixed already , how many mls would we need then? Thanks for any help guys.
