Yes I saw Lesso post and agreedRoster he is growing under 20/4. If he changes his light to 14/10 his plant can definitely start to flower. I've seen it happen. His best best it to go to 16/8 first fo a week and then to 15/9 for a week and then he can go to 14/10.
He wants to put them outside. If he has them under 20/4 and sets them out side where it's 14/10 the plants can go into flower. It's happened to me more than once.
I thought he was doing an inside grow
