Whats wrong with my plants?

All of my plants are grown indoor under a 90W led and 4 100W cfls. They are in vegetative stage and i water whenever the soil feels fully dry. I give them nutes (fox farms grow big). After looking at threads on RIU I believe some of my plants have a Magnesium deficiency but i am not sure and I want to be sure before i treat it in case the problem is nute burn or something else i could exacerbate. Note: these pictures are of multiple plants and I think they have separate problems.

That's some bad nute burn. Looks like multiple errors. I would flush flush flush and back way off on nutes.

Also your Avatar is inappropriate. Imo

Looks like nute burn to me.

These look like a guy i know plants , he puts nutes straight from the bottle into the soil , Horrible...
Yeah Flush the shit out of it and when u do start back , start with 1/4 strength until u see fit..
Good Luck..

Yeah, flush with ph'd water. I like his avatar ;d

No, they all have the same problem: you. I don't mean that in an ahole way, it's not uncommon for beginners to kill their plants with nutes. Personally I'd start over if my plants look like that. If it looks like this top soil, imagine the hell they are going through at root level. Plants on soil barely need any nutes at that stage and unless you give them demi/distilled/RO water they won't have a mag def at that point either. Waiting with watering until the soil "feels fully dry" isn't something you should continue to do either.

Okay thanks for the input everyone, I just flushed the shit out of my plants so I am hopping they will start to come around and green up. I will try to lay off the nutrients for a while and i will update in about a week on how they are doing.
