They will continue to expand until just near the very end when they will just harden up further.
The main stalk looks OK, some of the lower bows might benefit being held closer to the light. Thing is, the stakes are late cause you don't want to jab too many roots at this point in flower. I would find the most vulnerable areas and try to carefully stake those if possible. Carefully placed strings can allow one side of the plant to support the other sometimes too.
Be sure air flow is maintained as low in the tent as is possible, don't know where you are, but if the humidity climbs, Powdery Mildew or Bud Rot (Botrytis cinerea) can also set in.
Remind the old man, did we flip after we sexed? if so, that puts you at maybe 4 weeks, and you have 4 or so to go. When she stops taking water, she is definitely done. You can also go by the color of the pistils, or the condition of the trichomes. There are many schools here.
I like to watch and wait until they stop taking water (or crash over and break).
