Welcome to AFN. I've not grown that strain but yours looks to be a bit stretch, indicating that your lights were too high during veg. At 6 weeks you are entering full flowering so the lights can be lower than in veg. Tell us what kind of lights you're using and we can make some recommendations on how high they should be.
Also, this thread is in the wrong forum, as Cannabis News is an information, not a growing forum. Moving this to the Indoor forum.
