That odor you are describing is chlorophyll being used up by the buds. Did you flush them at the end and did you stop feeding then N the last 10-14 dayâ??s before you flushed?

IF you answered NO then the odor is chlorophyll being used up. That is why we cure the buds to rid the flowers of stored up chlorophyll.

Watch for mold and moisture on the inside of the galss and as well as the buds them selfs.
