Thats cool dude my first attempts totally sucked as well,a white widow in an old cupboard that grew wispy buds under a crappy spotlight and one fluro tube.
It had crappy lil buds on it all wispy and fluffy but i thought it was great and it was really because it was my first plant.
I shouldn't really have sounded so abrupt in my manner but i meant no harm.
Do not give up and read as much as you can and try again,as time goes by you will learn to know what to do and when to do it naturally.
Fertilizer doesn't really matter imo in soil anyway i use plain old miracle grow and tomato food mixed with a little bit of molasses and mine grow just fine.
Try using a cheap water filter for your tap water,im wondering if you live in a very hard water area and your roots cant take up enough nutes from the hard water locking them out.
Anyway if you need help just ask around and you will get it,sorry if i sounded offish about your stuff
