how is your extractor fan hooked up?
Venting from the top?
I'll admit I know nothing about HPS. I've only ever grown under LED.

Yeah extractor is at the top I have just raised the light away from her slightly and opened up some of the vents on the tent hopefully that will help a bit those pics I just added are 24 hours after the original

I would concur with this. The fan leaves are curling downward, which in conjunction with the color, lead me to think Nitrogen toxicity. You've not been feeding at all?

Which vents did you open? You want leave all the top vents closed and just let fresh into the bottom only so you don't short circuit the airflow to the top part of the tent. Only reason I know this is cause I've seen it messed up lol.
