I agree with Tom: you're probably not going to get as much bud as you think you are. This is because you aren't going to give your plants enough time to grow before it'll be time to harvest. If you get two ounces from two plants starting at 12/12, that'll be a miracle.

Not trying to crap on your grow, it looks like a great setup! I would reconsider the 12/12 right now. If you're in a hurry, let them grow on 24/0 or 18/6 for 3 weeks, then put on 12/12. You'll get a MUCH bigger yield.

Good luck!
