Cal mag last couple weeks of flower

I’m guessing there is 2 weeks left of flower. I’m almost positive I have cal deficiency. Is it ok to use at this point? Seems like the good smell is not there like it was in early flower. Last last in soil other than mother plant. There is brownish red spots here and there on leaves. Tips of leaves are kind of curling as well. Sorry I’m all over the place I’m stoned.

Post some pictures in natural light

The white powdery look is from when I put some organic dust bc of infestation

I’m going to post a couple pics in natural light this evening.
