The dreaded goo! I am 100% sure the water was decanted out properly! There was a fair amount of sacrificed solvent left in the original jar with the small, light green water layer. After decant, citric was added and it went immediately foggy and bubbled a bit. I took this for a great sign at the time, and was excited to see crystals, but alas, a day later there is just a layer on the bottom that looks bright blue when flashlight'd. A few things I could have done wrong looking back:
1- The cactus used was dehydrated extremely well before grinding. Perhaps too dehydrated? Is this possible?
2- The jars used were previously cannabis jars and despite proper washing, once the solvent went in it *appeared* in the green light that there may have been a small amount of cannabis crystals at the bottom, dried on to the jar. Perhaps these crystals held some water even though dried onto the jar? Or cann just having some particulates stop xtalization?
3- the citric acid used had an expiration date of 6 months ago on the bottom of the container. I didn't notice this until after use, when looking for clues of what went wrong. Could old citric acid maybe not work properly, or could it have absorbed some water during its apparently longer then recommended lifetime? It just said "pure citric acid" on the label- for sprouting.
4- I warmed the final salting jar up in a hot water bath after fully inspecting for water droplets on the bottom after decant to get it up to room temp. The walls of the jar were warm to the touch after the water bath. Could this stop xtal growth which seems to happen on the walls of the jar?
If I were to repeat this experiment I would be careful to not repeat these mistakes. Do any stand out as the definite culprit?
It looks like the best advice now is to decant off the solvent from the goo and add fresh Ethyl and hope this sucks some water or citric acid from the goo? Is this still best procedure?
In the mean time I added 10 more grams of citric and shook vigorously, hoping that would do it. Alas, it looks like no crystals and more blue bottom layer
