6500-6700k ARE plant grow bulbs. I would do two of the 6500k, and one 10000k, and one actinic. (If you have fish with blue in them, this should really bring it out) Or 2x6500 and 2x10000

Generally, yes. There are some 'plant grow' lights that are more in the yellow-red end ~2000k-4000k. Most people seem to agree that ~6500k is the best for plant growth.
