I have 36% nic juice.. does that mean I have 64% PG and 36% nicotine? So I want 60/40 juice. On my caculator I enter 40% VG, so is it assumed that the nic juice I ordered is 64% P/G? So how do I enter my flavoring % and come up with 100% when the PG/VG already adds up to 100%? know what I mean anyone out there?
