Maybe letting it finish growing is a good idea. You might get some good experience from seeing the plant grow to full maturity (and it'll probably make your next growth a lot better!).
If not for the flower than for the experience (bonus: you'll have bud to smoke anyway!).
Something that helped me grow when I first started was watching youtube videos. Seeing people do things and explain things in video might help you understand the information better. Just a suggestion... Good luck!
PS - look up "Mr Grow It" on youtube... It's a good place to start.
