The plant looks fine. The larger fan leaves mean you may have a temperature problem. Like temperatures about 83f for extended periods. Try adding a few cool white shop lights from HD or Wal-Mart with your grow light. The more lumens you can use the better. IF money is tight look for the Lights of America FluoreX security light. Its 65w of FluoreX they claim equals 500w of light. What I do know is for 40 bucks they work just fine and better then just a few regular fluorescent lights.
