Hi, there is no Iron Rule, in when and how you send your Girls into Flower. Most Growers look for their Setup and Space and if they are Ready< with their Training ( LST, Topping etc.)
So it depends in you. As you havent done any Training on the Plant, and you like her that way, well lets go. But i would do some Toppings on her. But just do what you feel comfortable with.
Greetings
