you dont need that much light for vegging, but i'd go to t5s if you can, (the small fluorescent tubes) they have a much better spectrum and are more efficient than t8s. when you go into flower, you're going to need a lot more light than you have now for sure.
for veg growth you can use almost any 10-5-5 type fertilizer as long as you're careful not to use too much, usually its a good idea to start at half strength and work up from there. again, when you hit flower, you're gonna need some good nutes, or the knowledge to make your own, which is an enormous pain in the ass.
and get yourself a cheap ph meter, some plants seem to almost ignore ph fluctuations, and some don't like it at all. make whatever nutes you end up using, then check them, if you're using soil , somewhere around 6.3-6.4. if you're using coco, 5.8 is considered perfect, but i actually intentionally bounce between 5.5-6.0, to prevent lockouts.
