Are you wanting to make a base that is just your flavors? If so, you can click the blue wrench on a recipe and click “Make Flavor Base”.
If you’re wanting to make a nic/pg/vg base you could create a ‘test’ recipe, input everything and a dummy flavor, then mix everything but the flavor together. Your rationale for the 80/20 at 3.3 seems sound and would at least get you in the ballpark. The closest I’m getting in the calculator is doing 4mg at 85/15. Doing 3.3mg at 80/20 will only let you make 2.8mg at 30/70 but that seems close enough. More specific math, I can’t offer at the moment cuz I have to run to calculus class. LoL.
If I was going to do what you were doing, and my nicotine was 100mg/ml I would basically mix like the following (I just used Juicy Peach as a reference for whatever your flavor base is/was):
Thanks to everyone for your help, I think I’m staring to get it now!
If I needed it to be exact I would measure but I do find it a hassle having to get out the gloves and nic every-time with all the other safety precautions!
Choose option “C” to calculate the concentration of the final solution, then you are able to change the inputs to see what works for you.
So in my example i would need to make up a premix of 77.8/22.2 (VG/PG) @ 3.333% Which when added to 10% concentrate mix would give a perfect 70/30 @ 3mg!
