There ur plants do as u see fit, but if we're mine I would wait till I see about 20% amber trichome and I'm not seeing any amber, if you want a head high you can chop when all trichome is milky, if you want a body high you want some amber trichome, if it were mine I would wait, allso a week to 10 days before you chop you flush out your plants, use cold tap water this will not hurt plant, reduces any foxtailing and helps turn pistils.
