Rust colored spots.

Can anyone tell me what this is???

That's Calcium deficiency that's been ongoing for some time.

Medium? Nutrients? pH?

It also appears as though you've got a white cat that's been allowed to frolic in the grow space. Irrelevant to the problem, but hair tastes nasty when burnt.

Big bloom and tiger bloom and I got cal mag to correct the calcium deficiencies Because I picked up on it earlier. So I assumed that was not the problem. I usually ph around 6.2-6.5

and white cat? I don’t have a white cat. And it’s definitely not frolicking. Haha

Mine look similar when I overdo Grow Big, looks like a little bit of nute burn

Your plant looks awfully green for being in flower...perhaps your N is locking up your Ca. Either way, as mentioned, it's showing short on Ca. Be careful how you attempt to rectify the problem as typically Ca is paired with N and you don't need more of that (N),...Good luck.

I don't see any claw leafs per se, but like @CannaCountry said, they definately have enough N.
If I were a betting man, and I certainly am, I would suggest you look at your Ph.
