after color change. is this normal. i went from a small jump start grow light in my window to a 400w HID light. the light is about 3 1/2 feet above the plant. there is a metal haloyide light in it.

The light is too far away.

My Serrano also turned yellow like in your picture but im not sure why? i hope its not Too much nitrogen or deficiency of a nutrient

Are they any nutes in the soil? How often are you feeding them? Looks like it needs to be fed!

 

[Hendrix1326]

Looks like it needs some water, brotha! Thirsty plants will become yellow, just as surely as if they're not fed enough!

 

[Dulac]

Yeah, that plant is thirsty.

Edit: Don't worry it will turn a lovely green after you water it. Give it a day and it will look nice and green.

I've seen this a few times when I overwatered my plants. That leaves you with three things that could be the cause... too much water, too little water, or too few nutes.
