What are those yellow tubes hanging in that picture? Is that some kind of bug catcher?Next time start in smaller pots and work your way up to that big momma it's in now. I would of used at least 2 smaller pots before I got to that big one.
At day 42 that hopeful girl should be larger then it is.
These girls are just day 29 a week or so after the second transplant in final pots.

Even though you got green it looks as if you could use more N(grow nutes) before flower and grow them out more.
Another 2 weeks I'd say.
