Awesome looking plant! How long have you been flowering? It looks like about 4 weeks. What kind / how many lights are you using? How long did you veg for? I'm a noob too, so I can't really comment on how much longer you have. Others estimates seem good given my limited knowledge. I'm 4 weeks into flower, and I'm really anxious to see what they look like in 3 or 4 more weeks. Please keep us updated with pics; you are doing great.
Check out my grow if you get a chance:
