Once plants start developing flowers, they need to be given bloom nutes and your diary doesn't show us what she's being given... but the NPK of what you say you're giving her does not tally with what bloom nutes usually are. She's desperately hungry at this point for a lot of P and K and not much N....
Aside from that, I'm concerned that you're only feeding her once a week, like my other growmies are. You should be practicing a routine of water/feed/water/feed - so in any given week, she may be fed 2 or 3 times or more (when my ladies get that thirsty, and they do, I'm giving them something every single day so they often get fed 4 times a week!). Only give her the calmag, though, once a week...
So get some bloom nutes into her.. and give them to her every other watering.... she'll really thank you for that!
Good luck!
