plant looks good. ph should not be 7 if you use nutes, they bring it closer to ~5, so go easy on them.
the smart pots will let the water drain out, which is a good thing. cannabis likes the soil to get dry before the next watering. if you watch how much its drinking, youll be ok. water deeply just till you see tiny bit of runoff, and then let it dry out.
it may just be time to harvest. lets see a zoomed focused picture of a cola.
about a week prior to harvest, skip your watering to speed up the drying process of the fruits. no more nutes from here on out. id say another week, so give it one last good watering!
