man I? would ditch that strain and get a indica one, your setup aint that
bad and a simple one will work, so I would say bad genetics. I would look
into putting some mylar up and a input for air to cool it when the lights
are at the hotest point.

6 weeks in to flower? dont waste ur time, that looks like strain grown for fibers not buds, with that light you should have some donkeys at 6 weeks... hermie/male/female? who cares ur just wasting ur time at this point. start over with good clones of a known strain keep ur temp range in controll and give them some nutes for god sakes not to offend you in anyway... looks to me like ur seeds/clones were no good to begin with... good luck on ur next attempt, it will only get better

I cant believe that no one realized that was a Sativa dominant plant, it probably needed another 4 to 6 weeks to flower, it most likely would have budded like crazy from the looks of the plant, though it could have used more light in the last 2 weeks of that extended period. They can take up to 12 to 15 weeks, but its well worth it. Anyone who has ever smoke a Sativa dom, they would fully agree. Kick your ass high!

OH, wait, someone did say that, so I second that. Even though this thread is way past old, hopefully someone learns something.
