Recently started working in the processing side of cannabis after years of working on the cultivation side. I am learning on a PX10 precision extraction, and on one side it is producing darker oil. I've tried cleaning the hose lines from material column to crc column, and crc column to collection/recovery column. I've cleaned the center plates on the crc columns, and I've cleaned the filters and bowls below the material. I've also done a degas on the solvent columns, and a dry run through the machine. Even after I did all of this, I'm still getting darker product on the same side. Any help or suggestions would be appreciated.
