You likely need to provide more light than one grow light and ambient window light. That said, it doesn't look unhappy. You will need to get a non-organic based fertilizer as the soil doesn't have (or is very limited in) the fungal or microbial growth to help process the organic fertilizer into usable form for plants. Osmocote Plus , Dyna Gro are two commonly used, which also have trace minerals necessary. Be careful with watering, as root rot is the common killer of all house plants.

For sure, your plant needs to settle in (gets it's roots going into the pot) before you can seriously expect flowering and fruiting. And for it to hold fruit to maturation, usually is a few years after its been growing in it's pot.
