Help!! W/Plant Yield w/pics

Hey this plant is only like 30 inches tall already has 3 colas and 8 off shoot popcorn buds frosted with crystals, These pics were taken 3-4 days ago and shes grown since then, 3weeks into flowering. THIS IS ALSO AN UNKNOWN STRAIN... WHAT SHOULD I EXPECT WEIGHT WISE WHEN I HARVEST HER!? THANKS ALOT!

There is really no accurate way tot ell fromt eh pics, but I average 2 or 3 ounces of dried manicured buds from my Indica strains adn I did get 6.9 ounces once from one plant.
Is that a Indica or Sativa?

somewhere between 1 gram and 1 lb.
