Help my plants

What is wrong with my veg room the plants are having a disease or some shit in there, this seedling has some type of deficiency what is it? Can it be from fungus gnats I have been having a problem with them.

appears as so. dosent look like a disease prob. add some neem oil or similar bug stoppers. should clear right up.

I used diameteous earth and yellow sticky traps already and they still are alive.

If you do have a fungus gnat problem try using some of this http://www.amazon.com/Mosquito-Dunks-117-6-Bits-30-ounce/dp/B0001AUF8G
i started using these once a week on my plants with those sticky traps and it worked amazingly

cant tell really but if its a fungas get some serinade , longer you wait worse it becomes , thats with anything really .

maybe use the force yoda
