does this look like calcium deficiency?

the plants are 16 days in since I switch to 12/12. the plants look super healthy jus this couple of leaves look like this. I also foliar feed once in awhile jus for extra boost. I have a feeling it's from foliar feeding but I want the experts thoughts on what it could be. I'll post pics below.

I think that is Calcium deficiency, Hit those ladies with some Cal-mag. I think Calcium is overlooked often enough. I hammer the Cal-mag to flowers, it really helps the Hindu Kushes flourish. Lots of indicas eat the Calcium up like crazy.

Also I cant see the pics that well, but there is little whitish specks on the leaves, no chance you have some thrips or something like that as well? I hope not, but look around!
