Need help! Grow tent Issues !

everything in my grow has gone wrong!

so far i'm growing in my room, the rooms is kept at around 70-73..
my grow tent is 3 feet wide 3 feet deep 6 feet tall. i have a 1000watt mh bulb in a cool hood i also have a carbon filer and in inline fan with around 450 cfm..

my temps stay in the 90's..

mind you the exhaust hose goes out a window

i also have a portable a/c that was pumping a/c into the tent but wasn't really helping

im willing to take any advice and to answer any question.

this is my setup.
