Just keep doing what you're doing as the plant looks healthy. Don't be like many growers and start dumping a bunch of stuff on your plant thinking that more is going to be better. The leaves look nice, no burned tips, nice green color. Keep them that way. Like
@Renfro said you want to make sure it gets 12 hours of dark so it doesn't go back to the vegetative stage. And you will need some kind of support later in flower. Other than some training that could have been done earlier that plant looks great for your first grow. Good job.
There are people on here that have been growing for years that can't keep a plant as healthy as yours. Well done.
Good luck with the rest of your grow.
