Spliffseeds AK! Come check it out.

To me it's mean you are under feeding , I mean I can see magnesium def , N def , traces elements def, I would feed more before the flush. Concerning the leaves , the plant did not let them fall down so she needs them , she is sucking the last nutrients out of it ( sign that your feeding is on the low because she's near the end but not that lose to start that senescence aka late flowering yellowing ). Unless 70% of a leaf is damage the plant will use it
