Is this a Cal/Mag deficiency problem?

Hey fellow growers!
I'm into week 4 of flowering, I don't know the genetics of the plants cause it was a feminized grab bag.
I've been using ALL MIX from Biobizz with a little compost mixed into it. I supplement nutes with biobloom and topmax from biobizz as well.
I'm using mars hydro LEDS too.

So I've been noticing these little brown spots popping up on the leaves in the middle of the plant, not all of them but two for sure and one is getting pretty bad.
Before I order some Cal Mag (which I've never used before in previous grows) I wanted to see if the rollitup community could tell me what the deal is and if it's possible
to just let it slide until harvest. (which should be in a month or so)
Thanks for any help or suggestions as I'm kinda at a loss here.

Oh yeah and here is a pic of the second plant that's having some issues...I'm not sure if it's the same issue or not. Any help would be greatly appreciated! IMG_0506.JPG
