Need help asap!!! Please!!!

I had to go out of town for 2 days, and left my roommate in charge of watering. He said he watered one day while i was gone, which i confirmed was okay. however when i returned all my leaves were curling and completely yellow with little brown spots. i'll post pics. i know my pot is small, but i've flushed and haven't given any nutes since. i have no idea whats going on, and i'm afraid it will dramatically decrease the enjoy-ability of the buds.

help me obi-wan kenobi, you're my only hope

A better pic will help. under white light not HID please.

okay heres another picture

2 days to that..yikes.. pH? what a mess.. P? K? Mg? Look that the sticky of def...

damn...buddy...she look terrible.

either you got a case of lock out and your now P def.

Mg def can run through a plant pretty quickly. yellowing, upturned leaves, and i do believe i see some chlorosis. its bad whatever it is. its early and i'm high......................

would you guys say that she's a goner? i mean the buds look pretty decent. are they gona smoke terribly?

and what can i do to fix this?

A guess is flush with proper pH water. Then some mag/P/K. Looks like hell and those leaves won't recover. May be rootbound to go along with it.
