My girlfriend was making e liquid and accidentally added pg to vanilla custard cap v2 . The ratio was a 30 ml concentrate bottle with 6 mls already used and 7 mks of pg added.

Soo.. We usually add 3ml per 30ml bottle, I was thinking of shaking it up real good and now adding 4ml per 30 ml.... Does that sound about right?

Right doesn’t really apply here. It’s all about what you like

24 mL of actual concentrate in 31mL of total volume creates a diluted concentrate 77.42% as strong as the original. That means you would want to add an extra 22.58% to equal the original undiluted strength. 122.58% of 3mL is 3.68mL.
(I think(?) I got that right; I would welcome someone checking my math.)

Guessing 4ml is close enough.

Here is how I would calculate it. The original amount of concentrate is 24ml, that's 8 equal parts of 3ml. Now take the new amount of 31ml and divide by 8 = 3.875ml.

eta: Here's the math (31/24) x 3

You used to add 1/10 of your original 30ml when it was 100%. Now it's 37ml total. 1/10 3.7ml.

3.5-4ml is close enough for your guess of 7mls added until you taste it.

I'd start by diluting a bit less, in case you wind up loving a slightly over flavored mix (you never know) and then progressively dilute and taste honestly.

I'm sorry. I hate dilutions myself although I have done them on occasion. Good luck,

Anna

Am I the only one thinking someone found a way to make us do their maths homework? Pretty good try I must say, almost fell for it.

Mine doesn't get them the right answer just checks the ballpark to say the others are close enough.
Pretty interesting story problem if it is for school.
I was going to say obviously not a real Dr if they can't do that.

Thanks Az! That is a lot cleaner, and more accurate.
