Very pretty buds,

Looks to be some excellent smoke, but your right the yeild is very low at less than 2 oz a plant.

The only thing I can see as a cause is veg time! Your Plants looked very healthy in previouse pics, small though.

A suggestion is take 2 cloans of your most favoite for a total of 6 to 8 plants and veg and LST them out till they resemble small hedges then at 16'' tall go to 12/12. You saw how I did it and got over 2 Lbs. out of 9 plants. Keep in mind that grow took me almost 16 weeks of grow time.
