Just keep an eye on her. I've had some autos run out into 100+ day range, even a few indica autos. You've got some time left. If you have a jewelers loupe, start checking tricomes daily to see when they change. Pistils are an indicator, but I usually couple the decision to chop from tricomes turning amber, pistils have curled & browned, leaves start to fade, and she will stop drinking. All things together give you a clear picture of when to chop.
My guess.. 2-4 weeks remaining, but that's a total guess...
We'll all be following along though. Ask & share if you have questions. This whole group has an amazing wealth of knowledge.
