    Bentonite clumps.
    Calcined clay is like ground up clay bricks.

    If that were N deficiency there'd be a more smooth fade of yellow at the bottoms to healthy green at the top. Especially with the bottoms br ing that yellow. This localized yellowing, especially with the necrotic spots that are starting to develope, are classic signs of cal/mag deficiency.
