Time will def tell, things don't look great though. either way just learn from this for the future. I think you've definitely shown that you have much to read, you can't just put a pot of soil in your closet with a light and get results. You have much information to sift through, you need to learn about this plant as much as you need to look into grow room setup. Without all the proper info you will just run into deficiency after deficiency, and probably have a rough first flower...
I started the same way, found bag seed in a good bag and they went into my window sill. After thoroughly ruining one of those I started doing research everyday after work. My girl was mad at how I never wanted to talk because I was busy reading... If I were to start from scratch I know I'd start with a month or 2 of research, and I suggest this for all looking to start. It's not cheap setting up even a cheap operation... I wasted money and time trying to set up a cheap cfl grow, wrong bulbs, short cords, no place to hang them. Eventually I said enough's enough, I've spent my time and money on this and I'm no where. So I bought a proper ballast and bulbs, 4x4x6.5 tent, blower fan with a carbon filter, and all the other odds and ends. Wasn't cheap but it was worth it, no longer fighting my environment for proper conditions. Plus they say loose lips sink ships, well stinky closets are up there too in my opinion...
