Welcome halo. You made my brain hurt.

If you add 10 mL 100% VG, you'll end up with 40 mL of 18mg juice with a PG/VG of 60/40

ETA: Here's the math
1. 30 mL of 80p/20v gives you 24mL of PG and 6mL of VG
2. You want 60% pg, so take your 24mL and divide by 60% (24 / 0.6) to get total volume of 40mL
3. To get total volume of 40mL, you need to add 10mL VG to your existing 30mL
4. Started with 24mg of 30mL juice -> 24 * 30 = 720 total mg nic
5. Now, divide total mg nic by new volume of juice -> 720 / 40 = 18 mg juice

Lol, my brain was at near bursting point also. I was working out in % and ended up at 19.2 mg by adding 20%/ 6ml of vg to the mix. It all sounded wrong to me and probably was. Thanks for the math lesson i really need it today ( the perils of too much sat night alcohol) many thanks for your time and answer.

So what if I wanted to make the 80 pg/ 40vg into 60 vg/ 40 pg? What mg of vg would I add and what nic mg would it make? Sorry for the dumb blonde Q.

Welllllll, not quite sure how you can have 80p/40v since that adds up to more than 100% :confused: ;)

I'm guessing you are talking about the original 80/20? Same philosophy:

30 mL of 80p/20v is 24mL pg and 6mL vg
You want the 24mL to be only 40% of the total liquid volume so divide 24 by 40% (24 / 0.4) to give you 60 mL total liquid. You only have 30mL now, so you would need to add 30 mL of 100% vg. Since you're doubling the volume of liquid, you'll cut your nic in 1/2 and end up with 12mg nic in your 60 mL juice.

HTH :)

Lol, I did tell you guys I had a hangover yesterday. Yeah it should have read the way you answered it. My brain had at some point melted I think. I've been vaping for 4 years but never adjusted shop bought juice, so it was more of a feeler post to see if any of you guys had the correct info. Thankyou for your patients and thankyou for a well thought out reply. Ps I do love the site and have browsed without joining for ages. Glad I've joined now and hope to melt your brain (if I aint already) in the future. Many thanks again from the halo17.
