There will be no definitive answer as it has only been 1 week and 3 flushes mean you have likely washed away any residual nutrients. Your leaves will probably start to yellow quickly but without seeing the plant it will be hard to make any reasonable observations. Are you seeing any milky, hazy, or cloudy looking stalks or heads in the trichome clusters especially around the calyx’s.
one of my chief complaints over the last crops has been the remarkably long time periods required for amber coloring in trichomes to develop, which, is more of a sign of chemical change in the plant and it’s continued maturity. I had prepared a few labels for curing that I had over a full month difference on.
