That bulb will grow that plant, a more efficient higher wattage bulb would allow it to grow more vigorously... but it's possible to get something out of what you have going on there.

What I mean is, you have one 85 watt bulb on one plant... Sure that's enough to veg and flower her, but doing something as simple as upgrading to a 150w/250w/400w/etc could easily up your yield, or even adding just another 85 watter like you have would help significantly in your plants development.
