do i just add concentrated nic
juice and flavoring to the VG to make
juice? is there a step that im missing?
Well, aside from determining your desired PG/VG ratio along with your target level of nicotine and whether that nic base is PG or VG... Not to mention the actual amount of various flavoring in what proportions to your desired final flavors...oh that and mixing, testing and finally tweaking, additives and steeping the liquid...yeah thats all you need to do. LOL.
I'm of course, jokin' around. We all want you to have the most amazing DIY juices but there is a little more to it. Always happy to help if possible.
Seriously, In essence, what you said is correct. However, there are huge steps between those that will make or break your DIY mixes. There are stickies in this forum as wizard mentioned. If you haven't already, you should have a good long look at those.
Best Of Luck!
