I grow in soil and stop amending about 4 weeks out from harvest. Amendments take time to break down so its not a 100% stop feeding.
If you are growing with liquid nutrients you can stop feeding last 2 weeks, but don't flush the soil its useless and dumb. just give them water but no runoff. just let it use up what it has left in the medium the start its fade. Flushing is to aggressive and does not strip or remove anything from the plant, its just not how it works. it does deplete the medium and the startve the plant, and plants with no food can't grow or make new trichomes or terps.
Good Luck!
