Hi, there’s no need to be afraid of it, as others have written, the mix is very usable, and the 70 VG / 30 PG mix for great vapor will surely be good for DL. 
(I wouldn’t get hung up on the decimal values for VG and PG, but you’ll need precise measuring tools for that anyway, which you’ll need for the other ingredients.)
If you still want a pinpoint accurate recipe despite this, then in order for us to help you meaningfully, you would need to specify exactly:
- How much liquid you want to mix (e.g., 100ml)
- What booster you are using, and what its composition is (e.g., 30 PG / 70 VG? or something else?) Also, what is its strength in mg?
- What flavor you have, what it is based on (e.g., PG?) and what percentage you want to use it at.
I’m happy to help you calculate if it’s still relevant.
