Gail, I have a silly question. What are you planting your seeds in?
Mine only get leggy if their potting medium is too rich. You're perhaps not incorrect about the light, but I would check the potting medium first.
As to the light, though, in my experience, you want to avoid any more red spectrum light than is natural for, say, sunlight during the vegetative growth. Red becomes important for flowering, whereas blue is primarily what is desired for vegetative growth.
If someone has more in-depth information on this, it would be good. My experience is limited to niche applications, and it would be good to get some breadth.
