Hey there DMT-nexus! I was wondering if anyone could maybe point me in the right direction, as this is my first caapi extraction and so I'm a little stumped.

Here's what I've got so far: I had about 450 grams of yellow caapi from *k1w1* that had gone moldy with some sort of trichoderma, which upon extensive research I found that there are no real toxic varieties of trich (am I correct in that? Would anyone know? It is such a common fungi we are all eating some of it every day I would think.)
I opted to do "Enoon's cold caapi tek" to reduce my propane use, as fuel costs are getting crazy and we use enough cooking food. This tek involves several 72 hour room temperature soaks in 3% acetic acid solution, and then optionally (?) reducing the collected pulls. I did 5 vinegar pulls and reduced to about 400 ml.
At this point I decided to use the precipitation method in gibran2's "Easy caapi vine extraction tek", basifying with a NaOH solution of 5g/50ml, removing the soluble impurities with water, re-acidify with vinegar, and finally proceeding to freebase the alkaloids out of solution. Here's where I ran into trouble.
The color did not change to milky, and there was no obvious precipitation. The color actually darkened somewhat and there was no precipitation. I waited about 24 hours to see if anything would come out of solution, but nothing did. I decided to make another 5g/50ml NaOH solution and add it very slowly to the mix. The color lightened a bit, and there was some precipitation, but not the huge billowing white cloud that I know should have appeared there, both from pictures in the tek and my experience in harmala extraction. It's been a few days now, and I think all that will come out has come. And its not much, and the color is orangish-yellow.
After thinking about it, I am wondering if the fact that the only solvent I used was 3% vinegar solution , the pH is probably somewhat off. I've added a total of 10g lye, which seems like enough to seriously basify it. This is mainly illustrating my need for some way to get a way measure pH! I actually have a nice pH meter, I just need the calibration solutions!

Anyway, barring getting the solutions, which would take money I dont necessarily have to spend, what do you think I should do here? Add more NaOH? I would have to do many many purifications if I did. Has anyone run into this before?
