help my roommate dried out my plants

i was gone for 4 days and my roommate allowed the plants to dry out completely then watered with a gallon of water with mg fert in it which i think might have given it too much nuts.

*used only half teaspoon in the gal

is everything going to be ok from the pics because some of the under leaves are lookin a lil off with burn spots.
the last pic the plant got close to the light do u think its nute burn, light burn, or repercussions from the dry out. the same ? goes to the other pics too

thanks

i just switched to 12/12 because of time and size constraints so will anything be affected or will it all kinda be ok in a lil bit

personally id say its from the lack of water, but also u shouldve just given it straigh forward water for a few days till it got better. how close is it to the light?
u mitv also stressed it, but it should be okay. good luck!

pics didnt upload for some reason but ill try again... they were touching so i backed em up. I have cfls.

ah, they look both light burned and nute burned.
move em a bit away, and just water them without nutes.
