Good question. The norm for CFL's is do 6500k for veg and 2700k for flower, but I've seen some mixed half and half or say 70% 6500k-30% 2700k for veg and vice versa. It's all preference. And i prefer the latter. I think a nice mix of full spectrum keeps the plants happy and bushy without too much stretching or loose nodes. But it's really your personal opinion you'll gain from experience.
As far as nutes go, I love my fox farms line up. But recently I've just used some nice balanced organic soil, Big Bloom towards the beginning of flowering, and molasses/water towards the end.
When doing organic soil however, doing as many different mediums as you can get your hands on is great: Perlite, compost, coco fiber, guano, bone meal, castings are just some examples.
