Burnt?

My fiance and I are growing Hydroponically and his leaves have curled upwards and are looking burnt on the tips. Can anyone tell us what's wrong?

Here are the conditions:

5 gal planter
platform holding a quart sized container
River rocks & glass beads in qt cont.
under a vanity
heater between 80-90
Miracle grow enough to make water viably medium to light blue
Spring water
Black light and energy saver light 60wat

it's a G13 plant

Almost sounds burnt but a pic would be real helpful. Your not planning on doing much with a 60w bulb right? If so your gonna need a few more :D
