If your going to flush the plants because you read that flushing is benificial to taste and or quality dont waste your time.
The act of flushing is not based on any of the principals of botany nor has it ever been proven to enhance taste or quality in proper blind tests.
All you will accomplish with flushing is to slow bud production to a crawl from starving the plants.
Ive been there & done that with absolutely zero benifit to taste or quality when comparing flushed vs heavily fed non flushed plants in blind tests with multiple blind test subjects.
I feed my girls right up until harvest but i personally like my girls to be big fatties,the added feeding goes a alon way in finish bud weight.
