Ive been growing off of 2/250 watt White fluorescents & 1/25 watt Grow Light also a fluorescent, with no problems.

If that is all you have I would start vegging the plants with just the 2/fluorescents then after about 4-6 weeks when the plant is near 8-12 inches tall, I would throw in the Flood Light for Flowering.

Budding needs lots of Light!
