Lol Holy Crap G!! That is gonna be epic! I love that you never topped it. You may end up with a 15 footer
Mine never doubled in stretch but she probably added 75%.
She's going to pull a lot out of that planter, if you have access to compost or some bulk earth worm castings you might want to keep fortifying it. This is going to be grande!
Some commercial top dressing may help. Something like Gaia Green Power Bloom, which is $60 CDN for a 25lb bag works well. It's 2-8-4 and Ikky loved it.
She nugged up nicely. I top dressed 1.5 tablespoons per gallon of pot size weekly and it worked well. Then capped it with a quarter inch of EWC every top dressing.
You need to spam us with updates Buddy, this is gonna be good
