Closet Issues

[PHATBLUNT420]

So basically i have a closet that ive tried to grow some plants in ,
i have yet to get a successful yield from my 3 attempts.altough i have transplanted some outdoors and they recovered greatly

The room is about 7Ft across and 6Ft tall 2Ft length
The light is a 400w HPS , the temps seem to be about mid 80's although i have no meter

I have gotten clones to Veg and even a couple weeks into flowering before they got bleached out and extremely vanished of Nitrogen to the point where they turned white and would turn into ash if you rubbed on it..

I think i have the height issued solved by SCRoG'n

i really want to get the closet up and running as its my only way to keep my meds flowing constantly ..

i would really appreciate help
