Help please

[taz96]

Ok, I want to make 100ml of Kreeds Kustard at 30pg/70 vg.  I have 72mg PG Nic and premixed Kreeds concentrate. 

I can't work out how to add the right amount of pg as calculator says I need to add more ?

Would some kind soul post the recipe for me pretty please. (I do know I'm being thick   ....again )

What % Kreeds conc do you intend to use ?

[Greg]

Oh and what mg nic do you want the juice go be ?

[taz96]

Greg I can't lay my hands on it but the mix he recommends to use at 16% > The target is 12mg

Perpetua I may have to go that way, my original plan was 20/70 but gave up after a few attempts with the calc. I don't know why I find this mixing lark so damned complicated.

[Perpetua]

Actually taz96 . . . . I've just tried the calculation again, checking the PG box against the concentrate element and it doesn't generate a negative figure doing that - perhaps try that first?

I'll pop up the figures:

16.67ml Nic Base
5.33ml PG
62ml VG
16ml Concentrate

To make your 30/70 blend @12mg.

Perpetua You are a star....thank you . I tried calc again and i still can't get it, not a clue what I do wrong.

[Perpetua]

No probs taz96 . . . . which calculator are you using?

Ejuicemeup I find works best for me:

Perpetua That's what I tried. I'm deffo doing something very wrong, I just can't fathom what.

[Perpetua]

I wish I could do screenshots taz96, but I can't.

Perhaps someone who is more technically able than me can put one up to show you what to check where . . . . first off I didn't highlight the 16% concentrate and got the same negative PG figure as you . . . . when I ticked that box in the first Flavour line - it went through fine.

I probably haven't explained that very well, sorry!

Perpetua  I'm delighted to know I'm not the only one who can't do screenshots.....lol That has made me feel soooooooooo much better.

Me and technology are not best pals

The reason you are getting a negative number for PG is that with your flavour and nic base you have reached 32.67% PG so it is impossible to achieve 70/30 VG/PG. 
The recipe above gives 62/38 VG/PG ... Leave out the extra PG and you can have  67/33 VG/PG by increasing the VG to 67.33 ml.

I also get PG errors for your mix, best PG/VG ratio I think you can achieve (with PG nic) is:
