Wrong ph, nothing else. Those leaf wont return, but you can push her to harvest if you start putting right one ... Adding calmag is not a magic stick, you can overdo even .... Thats definitely calcium issue.

Looks like a manganese deficiency to me. https://dutch-passion.com/en/blog/a-visual-guide-to-cannabis-deficiencies-n987
