Chopping and cutting down

Waaay over fed in general, so you will never get fading leaves until the plant is dying. Wait until there are 98-99% brown pistils/hairs, then you will be in the harvest zone.

It could be the picture but to me it seems like you still have an abundance of white hairs on your plant. If it were mine, I would wait until almost all pistols turn orange AND the leaves begin to fade. Even if its nitrogen heavy, it should still eventually finish ... although excess nitrogen will slow down maturation.

You need to judge your harvest time based of trichromes, and only the trichromes on the bud. The plant was fed too much nitrogen during flowering. So your leaves won't fade as whoever told you.
