Thanks for link! I'm just getting to where I'm ready to place an order and get started on diy juice. Do you or anyone else know of a calculator that would help me adjust an existing e-juice? Like if I have some 80pg/20vg 18mg and wanted to modify it to 50/50 12mg and not really worry about the diluting flavor or adding more flavor.
ejuice me up is great. You can just put in the top box :nic strength ejuice, 80/20 18mg in your example.. next box is target nic strength so put 12 then modify the target pg and vg to 50/50.. hit calculate. You'll get an error saying you cant really do 50/50 out of that but it will still tell you how much its off by (which in your example is not a lot at all).. Adding 30% VG to something will definitely dilute the flavor a bit though.. You can also save everything on your computer for easy access. Not affiliated just a great piece of software.
