Little help with calculations?

[canford]

Hi guys need a little help with the calculations, made up some juice using this www.postmodernsmoking.com/resources/advanced/diy-mixing-calculator/ which has served me well, the most recent batch been 50mg of forest fruits 70pg30vg 20% flavouring using 72mg pg nic base which I mixed at 15mg nic strength, how ever I need to change it down to a 12 mg nic strength, when I use the calculator it shows I need to add an extra 2.1mg of pg to achieve this, but the vg amount stays the same, this is the part I cannot get my head round, thought I would have had to add some vg. Also the calculator shows a reduction of 1.9ml pg nic base, Is there anyway to achieve the desired goal of 12mg nic strength as there is plenty of room left in the bottle. Any help on this would be great. Thanks.

Hi canford, here's an EJuiceMeUp recipe for your mix - it seems to work really well, with wide margins. Can't get it to copy onto this page but click the link and you should be able to access it!

ETA: yes I can (thanks again Super-Shiny!)
Hope this helps!

If I understand correctly you have made 50ml of 15mg/ml e-liquid that you want to convert to 12mg/ml?

If so you need to dilute it by 12.5ml with non nicotine diluents, making a total of (50+12.5)ml = 62.5ml of eliquid.
To keep your PG/VG and flavour ratio the same this 12.5ml should comprise of:

6.25ml PG
3.75ml VG
2.5ml PG Flavouring

Postmodern Smoking has got it bob-on, canford

You'll need a bigger bottle though, to get your 62.5ml in

That's great guys, love you calculator postmodernsmoking, use it all the time, the bottle will hold about 70ml so alright there.
