Between 1.4 - 1.5 ml.

17.61 -18.09 mg/ml would be the final strength.

great stuff cheers mate

No probs mate - 'tis easy with the "nic combine" feature of E-Juice Me Up.



Put your 10ml @ 10 mg in the top row.
Put 72mg in the second row, and change the ml in second row until result mg at bottom is about right - seemples.

(Should mention that PG/VG doesn't matter in this instance)

It is only simple when you work out you have to do it the wrong way round, by guessing the ml to add (if that makes sense)
