This is the last week of the grow. Tomorrow they are each getting a gallon of spring water after flushing them all with tap water. That's their last feed. I will wait to defoliate and harvest until they start looking droopy and drying out. Which last grow, took about 5 days. OR ... I might harvest in four days only because I know how long it is going to take to clean them up before drying them and Sunday is my only free day with abundant spare time for the job.
