Interesting stuff guys, followed the link here from another thread, agree with other guys here that you need to up your wattage a bit, also in my humble opinion its better to feed a regular small dose of mostly nitrogen right through the whole grow, but follow manufacturers recommendations from whatever product you choose. Good luck with this, I know that in Amsterdam, where I go for a break maybe twice a year , the Americans you meet almost write poems about the '' Sour Diesel '' that was around maybe ten years ago, I saw it in a coffeeshop and gave it a try and yes, it was quality, so Id be interested in seeing how this one turns out. As for the question you were asking at the start about yield, if you up your wattage a little and seeing as how you don't seem to be thinking of trying any such tricks as LST , tying or super cropping then it would be prudent to think around the 2 and a half to three ounces of dry cured bud.
