I like these pH strips: https://www.amazon.com/dp/B09ZXZNJRC?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_4&th=1 The outer layer of the cactus is a clear waxy skin that contains zero to trace mescaline. Right under that is the green flesh that contains the highest concentration in the plant. Its a pain in the ass, time and labor intensive, and an unpleasant job to cleanly separate the clear waxy skin from the green flesh and honestly not worth your time. I recommend continuing to remove spines and core and process the rest. Jiimz bridgesii should test around 2.5% on average but as low as 1.5% is not outside of the expected variation window. Consider: in Dr. Liam Engals testing of 26 specimens of TBM-B sourced from different growers, he found a high to low potency range of 4%. What type of cuts are you primarily extracting from? Mids typically test higher than tips or low column very old cuts. The right pH strips to make sure you are extracting it all will help rule one possible issue out. Sometimes if your paste is too dry it can take more pulls than youd think. Other than that, and the ethylene being discussed, I dunno, maybe you just have a bunk box. I would for sure save to plant or graft at least one of the twin spine cuts if you havent powdered them up already. But I dont see any glaring issues with your process other than the pH strips so I would lean toward source material being the issue. You could try some TBMc or SS02. But honestly getting massive 3-4g runs is not normal or expected. The people you see posting those are going through quite a few average or even disappointing runs to finally hit that one jackpot. So dont be discouraged.
