You should get more than that. Nirvana's Hindu Kush is my best producer. I never did a whole Kush crop when I was running a 1k light, but I got 22 ounces (dry) of NYC Diesel under that 1k light with six plants, and Kush is a better producer than Diesel. I have a six-plant Kush crop flowering now (day 31, about halfway done), under a 600-watt light, and I'm kinda expecting that to produce around a pound, maybe more.
