I think it is a lack of CO2, Ceg says holes in leaves are due to poor flow of CO2 or low level of C02.

Assuming this is not a result of predation by vermin invertebrates, it is due to poor CO2.

Increase CO2 injection, or add more liquid carbon, or reduce the light intensity, or improve flow/distribution or implement any combination of these.

I wouldn't blame the cory's unless they had turned vegetarian.
