Looks like you got seeds from the same batch I did. My TD.s are outdoor (started in April) and unusually huge, my largest plant is 20+ feet tall. They took forever to start flowering. The first 2 weeks were pretty slow going, I was wondering if they were ever going to make it. They are flowering hard now, but they still have a few weeks to go. I just hope they are done before it starts snowing! lol
I am a veteran grower and I have never seen anything like this plant. It grows straight up like a tree, no matter what you do to it. I have 1 that is farther along than the others. This was a very leggy plant, for the longest time I thought they were males and kept looking for balls. Flowering starts out typical sativa looking, then they all grow together on the branch into 1 massive bud. The entire plant gets thick & bushy like a kush strain, so weird. I am just now seeing trichomes. I seriously thought these plants were going to be garbage because there were no trichomes and very little on the one farthest along. Now, the trichomes are finally growing. Nice smell too! Very tangerine like.
I don't think light or nutes has anything to do with why this plant is taking forever to flower. My other strains are normal. Anyway, hang in there!
