You should chop now. Ideally you want mostly cloudy trichs with less amber and even less clear. Clear is precursor acids and are not yet psychoactive. Milky/cloudy is ripe THC. Amber is degraded THC, CBN. CBN is much less potent than THC. If you have very few clears left with mostly cloudy and some amber this is peak potency. 50/50 is a bit late IMO.
