The best sign of a good flushing is the color of the leaves.
They will fade from their dark green to light greens and yellows.
The purpose of flushing is to stop feeding them and make them use up their reserves stored in the medium and leaves.
A 1/4 strength (ppm) nute solution does this best, to begin with.
Plain water at first won't leach the salts and minerals like a diluted 1/4 solution will.
Keep the ppm's under 75.
Seedlings are fed 100 - 250 ppm's, so you don't want to keep feeding, but actually flush.
Run that for a day or few even, depending on how green your foliage is and how much you have, then reduse to plain water. Again, with low ppm's.
Try to time it with when you want to harvest, based upon the trichome colors.
Knowing your strain helps make that easy once you grow from clones.

i thought you said you were going to trim...meaning harvest. i agree with flogrows method of flushing....imo...harvesting a plant too early is not near as a waste as harvesting too late. i always allow a week extra after i think they are ready. i let my bubba kush an 8 week strain go for 10-12 weeks and was the best smoke ive ever harvested...was also the third harvest (bottom nugs)....better than the tops!
