never , keep feeding them lightly , flushing is a myth and seems crazy to starve them during their vigorous times. I do tend to back the nutes off in the very last week . The drying is the key to clearing all the harshness. low temp ( 19.°c ), low humidity( 40%) and slowly dried ( 10 days at least) The chlorophyll in the leaves is what gives the harsh hit. If allowed to be used up and eventually immobilised by drying , the buds will convert the small sugar leaves into a final snack and then a shirt cure in airtight jars for about a week and the terps will be properly available as the gassy smells get released during "burping".
