That is a low weight, even for sog. I've seen sog's that don't even veg their clones and they yield around an oz a plant. Though.. if you're running 3k of lights I'm sure you have shit tons of plants, so you're still probably pulling a nice harvest.

What is your average grams per square meter?

Also, depending on what cut of ogk you have, you may just have low yielding plants. Abusive's cut has pretty poor yields and I'm not really familiar with "Mysty Haze"? Is it a kali mist/haze cross? Either way.. hazes generally don't yield too well either.
Orzy Reviewed by Orzy on . Low yield OG Kush and Mysty Haze Hello there I am growing this 2 strains for the last 3 harvests and the yield is very small but the quality is the best I've seen and smoked in my life. I am getting between 7g and 14g per plant. Does anyone know if this is average ? What could cause low yields ? Thanks Rating: 5
