I would say she looks about halfway through flowering, possibly a little further along than that, but I would read your yellowing leaves to be a calcium deficiency rather than her attempt to finish up. What's her situation, what and when did you last feed her, how old is she??
Do you own Cal/Mag?? If not, stick a couple of eggs on the stove to boil, save the shells and get back to us.
