I harvest most of my autos around 14 weeks, but I’ve had a few go longer. It’s all about environmental factor plus genetics. I find it usually takes a few more weeks then what the breeder suggests- because at home we are not growing under the same controlled conditions the breeders grow with. It’s usually 4-6 weeks in veg- then 8 weeks to flower. Meaning harvests can usually range from 12-14 weeks.
You’ll need to check trichomes at this point. But she looks pretty ready 🌱
