Yes, I believe plant’s need more cal/mag during flower. This is when plants need it most. Especially if growing in coco.

Calcium and Mg are super important in flower!
Ca is a major ion that plays key roles in lots of metabolic and ion exchange processes in the plant. Mg is the same with the added requirement for chlorophyll.
Without the right amount of Ca or Mg in flower you can lower yields and potency/secondary metabolite production quite a bit.
Just like tomatoes can get blossom end rot without Ca in flower and fruit, cannabis needs Ca in flower to maximize the metabolic potential.

That doesnt look like Ca def to me, imo. Looks like maybe a potassium deficiency. Ca deficiency usually looks like weird light spots within the leaf :
