Are all the pictures in your week 7 the same plant?
If so, she's starting to flower, you can see the white pistils coming out on top.
G13 labs says her life cycle is about 70 days, that would give you about 3 weeks left but i'm sure you'll have much more time than that.
I've had an auto flower strain last longer than 3 other photo strains in the tent total of 15 weeks, but outside the same strain started flowering in the fourth week and was harvested at week 10.
Given the pictures I'd say she's just starting to flower.
Goodluck!
Happy Growing!😃🌱🌿🌲
