I agree with that. It's all about factors when it comes to the many nuances of growing in hydro.
I can try and spout out figures and such. but you all need to figure out what method or timing or even environmental choices on your own. If you need to flower like you say for space issues. I didn't say there was anything wrong with that...from seedling this is pretty immature. You need a minimum of 2 months to reach true, minimum age for flowering. It's funny I have this old marijuana growing book from some professor in the 70s. He let the plant go with 18 hours of fluoros all the way. It took a year for the plant to finish. It was comical...looking back on it, but this guy was a pioneer even though he was wrong in some methods. Bottom line. He grew pot and dried it, and smoked it. His own way. lol Peace Enjoy.
I would strongly recommend a cloning program so you had more mature plants
