I have a bottle of 18mg juice. I love the flavor and want to vape it, but it's too strong and gives me a headache. my ideal nicotine level is 12mg. If I were to reorder the exact same juice but in 6mg nicotine instead and combine the 18mg with the 6mg into a larger bottle, that would make it a 12mg nicotine juice, correct?
dumb question: mixing nicotine levels?

Yes I've seen a few juice manufacturers recommend that when their customers had a bunch of liquid already that was the wrong strength. It's like anything else in vaping, put thought into it and make sure your parts are correct for the desired outcome, and it will be fine I bet. Something I read one "chef" say was that shaking it well when mixing was important but also whenever you go to use the bottle, as the bases may differ slightly if time has passed between orders and one mg strength may be heavier, denser, etc. It's just a theory but most of us shake anyway before pouring.
It's great that you felt comfortable coming here to ask first, I hope more people do so.
Always shake the bottles before filling a tank or mixing. They do settle somewhat. You are on target with the same flavor in two nic levels. Add the two percentages and divide by two.
Whenever my supplier is out of my nic level in juice I do that. Time before last they were out of 11mg so I ordered a 50ml bottle of 0 nic and a 50ml bottle of 24mg and made 100ml of 12mg. I've done 16 and 0 to make 8mg and I've done 12 and 24 to make 18mg as I was reducing my nic level over time.

Not a dumb question at all. Everyone that every dipped their toes in DIY has probably thought the same question. I know I did. Here is a calculator that has helped me when I was mixing. It is easy to do. Good luck to you and happy vaping.

Correct, assuming you mix equal parts of the 18 mg and 6 mg juice. In general, the equation for mixing solutions (e-juices, in this case) with different concentrations of the same chemical of concern (nicotine, in this case) is (C1*V1) + (C2*V2) = (C3*V3), where C is concentration, and V is volume.
For your example, using 10 mL bottles of the two you wish to mix:
(18 mg/mL Nicotine)*(10 mL juice)+(6 mg/mL Nicotine)*(10 mL juice)=(12 mg/mL Nicotine)*(20 mL Juice).
Using the general equation, you can determine the final concentration of any combination of juices with different nicotine concentrations, even if you mix three or more juices with different concentrations. For three juices, it would be:
(C1*V1)+(C2*V2)+(C3*V3)=(C4*V4).
For four, it would be:
(C1*V1)+(C2*V2)+(C3*V3)+(C4*V4)=(C5*V5)
And so on.
But if you are not comfortable using algebra, an online calculator you can trust is your best friend.
