Agree that this could be happening if decanting was indeed done carefully. The goo from undersalting tends to be hard and doesnt move, while the goo from an improper fridge rest/decant flows more. Maybe we should simply update the TEK to salt with two teaspoons of citric acid?

During IPA re-X a pH strip may be informative. I'm going to guess that trimescaline citrate goo re-X will be neutral and mono-mescaline citrate re-X will be slightly acidic. If trimescaline citrate doesn't re-X well, adding citric acid before the cold step should crash the usual monomescaline citrate in cold acidic conditions, but not sure if a tiny bit of water will be needed or not (it is a hydrated salt in the usual TEK per NMR).

Overtime gardeners are going to keep on selecting the higher yielding cacti so doubling the teaspoons of citric acid may make it more future proof. This by the way is why citric acid is recommended, it has good solubility in EA and a huge process window for the lazy people among us who don't want to be bothered with careful measurments.
