Just stop fertilizing. I would only do flushing with hydroponics if I had been going heavy on the feed. I always back off N right before flower, and taper it down to just P. The last couple weeks I give just plain pH’d water. I live in a legal state so I can experiment a bit after my jars are full. The 3 plants I have hanging now went to almost 90 days. It’s really strain dependent.
