I did calculate this on a calc and left out the 15% flavourings on this mix ready for smaller 30ml bottles to add it later is this the wrong way to do it.Meh, why bother with premix?
Just a question, a 50/50 premix will give you a higher pg/vg ratio after flavouring and lower the nic. You also don't have much option to create higher vg juice for dripping and lower vg for tanks. It works out a lot cheaper to buy them separate and have greater control of a mix.
