Great first grow. If you make a few mistakes it can slow things downa bit. Not a big deal imo since they are looking healthy. I would forget the calendar and just focus on what they need and take them to true finish... meaning they look like the season is changing with yellowing and leaves, brown or orange pistols and ambering trichomes. She is behind, sure but she can make it to the end.
