30/70 pg/VG premix help me please

Hi I’m using a 30/70 pg/vg premix and 30/70 nic mix My flavours are pg based so therefore my overall pg % is getting messed up. More like a final 47/53 pg/vg am I right? I’m looking for overall 30/70 pg/vg. Can I just add more vg? Can someone work it out for me as I don’t quite understand it. I had 1 litre of premixed base and wanting to make 120ml bottles.
Been doing this for a while and only just realised that flavours are pg based

Did you check the appropriate boxes in the calculator?

Yes I did, does this give the desired 30/70 mix but I’m adding a premixed pg/vg mix

When I started mixing my own I somehow came to the calculations of: 87.96g of pre mix 30pg70vg
Nic 30/70:23.64g
Dragon fruit: 21.17g
Vanilla:3.02g
Strawberry sweet:6.05g
To make a total of 120ml juice.
Then only just realised that my 3 flavours are pg based and this is increasing the overall pg ratio.
My juice has barely any flavour.

That’s quite a pickle you’re in there Ben and somehow I don’t believe your PG/VG ratio is the culprit.

No matter what you make you’ll be faced with that same conundrum. If it were me I’d just buy a liter of VG and a much smaller amount of PG for more precise mixing. Then save that premix for mtl/pod style mixes where 50/50 is more common.

Using 100ml as an example, your 30/70 premix is 30%PG and 70%VG by volume.
By volume that would be 30ml PG and 70ml VG
By weight that would be ~31.08g PG and 88.27g VG.

IMHO, I’d suggest you should;
Read some beginner tutorials on using this calculator, and how to enter your flavor stash properly.
Make small volume test mixes before that larger 120ml amount
