HELP! My plant needs you!

This girl has been doing well up until the last week i have been noticing some color changes. instead of the lime green girl it was it is slowly starting to fade to yellow. what do i need to do?

Not enough info...what are you feeding? how often? Temp?

Could be a nitrogen (n) deficiency. What nutrients/fertilizers are you using? What is the pH of your soil?

Put a MH up. Your plant needs the UVB its not getting under an HPS or 2700K CFL or w/e, Im just guessing.

nah plants in veg do great under flourescents... plants look healthy actually slow down on nutes... what are u growing in woodchips?

those woodchips never let go of water- overwatering.
