Help diagnosing Nutrient def!

Ok here goes. I am growing in a stink bud JR set up nutes are AN grow micro bloom ph perfect, Botanicare Cal mag plus, and Dutch master zone. I am having I think to be a mag deficiency but im not sure and all of the guides I have read don't have a good picture of what it looks like and I know every strain is diffrent witch makes it a little more difficult. But Temp's and PH have been in check.

All pics are taken in flower execpt the 3rd pic is from a pineapple express in veg. And the Last one is some Bud porn for yall!
