Using both hps and tube flourescents during flowering

I have a 1000 watt hps for flower right now and put in a 50 watt tube flourescent in a spot not getting a lot of light. Is this ok or will it maybe confuse the plants since hps is summers light spectrum. I noticed two plants moved themselves away from the light (and wasnt because of heat because theres no heat).

Also, how do you install cfls in your grow tent? These things:
