Hey, first of all thanks for this great tool! It really is the best and most user-friendly soap calculator out there!

There seems to be an issue with calculating the additional lye needed then using citric acid in a hybrid soap.

When adding citric acid, the following additional amounts of lye (for every gram of citric acid) need to be considered.

1g citric acid = 0.624g NaOH
1g citric acid = 0.842g KOH


When using the NaOH calculation (solid soap) it is calculated correctly.
When using the KOH calculation (liquid soap) it is calculated correctly.

When using the NaOH + KOH calculation (hybrid soap) it is not calculated correctly.
It seems only the NaOH part of the lye is calculated and the KOH part is not added.

Thanks for looking into this.

There's no reasoning given in that article why it doesn't need to change.

Anyway, if I want to make a soap with a 60/40 ratio I want to keep that ratio that way, if I only add more NaOH it will skew the ratio. Therefore both types of lye need to be added in the appropriate amount.
