i want to make http://e-liquid-recipes.com/recipe/93540/Sour+Jolly+Rancher+%28Apple%29 but don’t have any sour, I read that malic acid was like tart and sour and made fruit flavor pop but does that mean that it can be substituted for sour and citric acid? Thanks in advance for your help.
Yeah. That is all that sour is…malic acid. You know the powder on warheads? That’s malic acid. 
From perfumersapprentice.com:
This is a sour note that can be used with other flavors for a “sour-candy” effect.
It is Malic Acid at a 20% dilution in PG.
Ingredients: PG, Malic Acid
Oh sweet I didn’t know that. Thanks. I’m gonna make this too http://e-liquid-recipes.com/recipe/71827/Red+white+n+blue+, looks good.

How much malic acid would I mix in with 30 ml of pg?
TPAs Sour is a 20% dilution, so if you wanted to do 30 ml, do 6ml of malic acid concentrate or 6g of powder and bring up the volume to 30ml with PG.
Are you speaking in terms of using the powder or the flavor concentrate ? I tend to use malic acid 20% at 1-2 % in my mixes it is by MBV
