If you want. General wisdom is that waiting until the trichomes are amber may deliver a more paralyzing body high, whereas harvesting when trichomes are cloudy white will result in less body effect, and more mental high. I dunno what to think about that. I see cloudy white in your pix.
Recently I seem to be reading an increased emphasis on proper curing being much more valuable than flushing. Some blind testing has suggested there is no point in flushing. I'm not advocating either way myself.
Nice looking plants, congratulations!
