Not knowing anything specific about your grow... I'm going with fungus. Look up Leaf Septoria. Obviously you have nute issues to with what appears to be a lockout but which one is yet to be determined with no additional info on your grow.

id say calmag and ph fluctuations. So the fluctuations could be causing a lockout even if you are feeding calmag you get the symptoms. I’d start ph’ing the water.
