Just from the info you gave, you need to veg longer and top more trim bottom branches off or SROG. Because of the 5 foot high room you need bushmaster bad. It keeps them from gaining height and so they bush out and go straight to maturity. Maybe get your temp down just a bit.

Doing very well you should get .5 grams per watt. 200 grams. more than that is excellence.
Patients in the veg time will pay off. I started very similar to you and went to hydro to find my way to what I needed. I do very well now and am finding my way to excelence.
