Could be wrong but looks like phosphorus deficiency to me. Get other opinions though.

Yes. I believe you are right. Calcium. Only because it doesnt look like it has spread to newer growth. Ca deficiency is mostly located in older growth and cannot be transferred to newer.

Phosphorus deficiency but more than likely phosphorus excess. What are you feeding?

Yeah, I’m thinking lockout. What ppm scale are you on 500 or 700? That’s why I prefer working with EC.
I would drop to 1.0EC/500 ppm(on the 500 scale) and work back up from there. Also I like to be closer to 5.8pH
