Too much UVB?

Hello everyone. Noob here, first post. I've got a White Widow, 5 or 6 weeks into flower and I just got a couple Repti Glo 10.0 UVB bulbs. I've read of problems with some UVB bulbs with a reflector, so I don't have any. The plant was doing quite well with some nice Colas, but when I came home the lights (4 32W 3500K 48" T8s and 2 26W UVB floros) had been on about about 10 hours. I really didn't notice it at first, as I came home with some 3000K lights and was excited about the improvement I was giving my girl when I noticed her branches were drooping. I put some dowels in to hold everything up and left the UVBs unplugged. They were both as close to the plant as possible without touching her. Will she survive, and is there any more I can do for her?
Thanks in advance,

Next morning: She appears to have regained her strength, and the whole ordeal has opened the top of the plant up so light can get to the lower buds better. BTW, this is a normal grow, my first. The buds don't seem to be aiming themselves at the light as they should, so I have a couple of dowels supporting some buds. At this time I'm just going to keep an eye on her, as she appears to be coming out of it. I'm obviously afraid to turn the UVBs back on; I'll have to do some searching on how long to have them on if someone here can't give me some info...but obviously not all day.

Flowering plants should have a 12/12 light cycle.

They are on a 12 on / 12 off cycle. They had been on 10 hours when I got home, had 2 more to go on the timer. Thanks for trying.
