For 3 months old, your plant looks R E A L L Y stretched. And the tiny pot is contributing to that, as well as the lack of light. If it were me, and I wanted to ever wish to harvest anything off this plant, I'd 1. Transplant right away (3 US gallon pot) 2. get rid of the aluminum foil and paint your walls flat white and 3. Get more of those florescent bulbs. You are going to need them to try to get this girl filled out.
