I'm thinking your on the right track. Back the light off 300w - 24"
Anything larger 30 inches. and cut the power back around 50% for a while then 70% after 3 or 4 weeks.

She looks a little deep green as well. Watch the nitrogen!

could be light or temp or both,..

The light is a 150 at 16 in at 75 % loght are gonna come on and imma check to see if the leaves went down but don't know how fast they change I had it at 100 then that started to happen and I lowered it, it is definitely high in nitrogen already got nute burn I think
