Is this a calcium, magnesium deficiency?

  1. What kind of deficiency is this? Should I be on my way to the store for some calmag? With the onset of flowering this past week several plants (different strains) are displaying this on some of the lower fan leaves. Please help! Should I foliar feed with something?
