Man, that's a perfect example of how to grow a small plant right.
I want like 16 inches, but damn dude that makes me enthusiastic for my results.
Really similar wattage breakdown to what I am using too.
I would consider trimming the lower leaves (some look like they had a shock or deficiency issue, they look yellowish in the picture)
Trim anything not getting hit by light at all. In my amateur educated opinion.
