im in the same situation. i am in my 8th week (51 days now) and since im only growing 2 plants under just a single 70 watt hps, the buds and yield are tiny. I have been waiting for them to take off,..but the swell already occurred.. i would say 60-70% of my hairs are red now,..trichs milky still...i might have an ounce off the 2 plants (kush,..is it normal for this strain to give so little,..or is it the light)...but man, when should i cut them. they are about 2 feet tall.top colas are only about the length of a lighter, but dense.
