Judge it off of trichomes and pistils and growth.
Most of the trichomes cloudy vs clear and some amber? Good to go.
Most of the pistils 70%+ dried off? Good to go.
The plant stop growing, thickening and growing up? drinking less water too and showing natural fade? Good to go.
Some plants don't amber up and some don't have strong pistil die back or have artificial pistil die back from other factors. so use your best judgment.
Maybe compare your plant with others from the same breeder, look at what their plants looked like when they harvested.
Good Luck!
