Congrats on your harvest, Stone!
I'm at 37.3N latitude so it probably will be a bit different for your location. I actually discovered some pre-flowering stigmas today on one of my plants. Actual flowering usually arrives about 3 weeks later. During last year's grow the three plants showed first signs of pre-flower on 6/16, 6/24, and 7/2. Flowering started 7/11, 7/16, and 7/21 respectively.
You'll still have time to get a nice size plant. Once actual flowering starts, my plants typically grow an additional 25-35% in height. If your plant is at 48" when flowering starts, then it could go to 60" by the end of stretch.
YMMV
