This is my second grow - 2x Golden Lemon Haze feme...

Looks like you are approaching peak thc potency of having majority cloudy trichs with a few amber. Being that you are in coco, a pre-harvest flush doesn’t need to be weeks long like if you were in soil. 5-7 days flushing in coco is plenty sufficient in my opinion.. that said you can continue on flushing while you keep an eye on those trichomes and harvest at the desired amount of amber in the trichomes. For a nice haze sativa like this - I prefer not to let the trichomes amber much. The amber color of the trichomes is the degradation of THC into CBN which gives a more sedate high rather than the more energetic and head high most are looking for in a sativa like this. If that’s what you are looking for, I would keep up the flush for 5-7 days and chop her down.
