She's looking tall and sexy! Looks like you'll avoid the problems of root lock etc.
A potentially winning tip: scoop out the top inch or two of soil, and replace with fresh stuff loaded with flowering nutrients. You could even take the cup off, wash the roots, and replace in a fresh cup of soil. Any little advantage that doesn't break the rules will get you not only closer to winning, but more likely to have a successful and healthy flower for medicine.
Looking forward to hearing how you enjoy the bud, and if you decide to add the strain to your regular rotation!
I generally do a different strain each time I grow, provides a little extra challenge and fun.
Grow in peace :)
