Spots on leaf

Hey guys Is this a calcium deficiency?

Are you in flower? Show the whole plant in a pic if you would.

Looks like cal def. add 2 teaspoon to gallon of water. It also shows a lockout.
That fade is nitro. I would give a slightly heavy feed with cal mag. Those leaves will not recover , they will drop off on their own.

Here's a pic of the whole plant. I'll give it extra cal mag and half strength nutes PHed
