Afghan Kush 1st attempt 3/4 weeks flowering

1st attempt at growing name brand genetics. Seed from World of Seeds its Been in flower 3/4 weeks and in 8" pot 50/50 perlite and peatmoss flooded 2/3 time each day with Canna aqua flores 2 part liquid. Plat is 12" tall and canopy is 18"x24". 600watt cheapo hps (switched on in 1 photo) and 2x 48 watt cfl in the back. was in veg for over a month but was starved and under poor light so remained quite small.

Any guesses of what this plant might yield and experiences with this strain please post up

WoW congrats on the sessy buds man looking really good. just a random guess i would say about... an 3/4 - 1 1/2 oz
