Hello ! Yes you are right, yellowing between veins and purple stems are the main signs of Magnesium def and they can be seen on your plant. Increase your cal mag amount and it will be ok :v::skin-tone-3:

Yes, textbook mg deficiency. You know, once the flowers have formed (3d or 4th week or flower) switch from cal mag to a magnesium / sulfur additive, like epsom salts.
