Hi and welcome!
I just re read joshisoms tek to see what you mean, and when it says repeat step 2, that is the step right above
Where it is adding the naphtha and shaking, let separate, shake, etc.
Once your mix is basified, you don't need any more lye.
Just keep doing naphtha pulls until the mix isn't putting out any more.
I would shake and separate about 5-6 times per pull while the mix is warm, and if the naphtha is very milky white,
Then freeze precipitate. If it's not then evaporate it halfway first then freeze.
Are you using acacia or mhrb?
Hope your extraction works out. The first one is just training!

Read read read and it will all come together.
Cheers,
