Why does my male keep eating the eggs?

[Shotput]

My male Discus keeps eating all the eggs and doesn't even attempt to fertilize them. I made this video can anyone tell me if my tank setup is off. Or if you can tell anything is off with my Fish.

I do a 50% water change daily.
I make my ready water the night before.
I use prime, discus buffer, epsom salt, normal salt to treat the water.
I feed a homemade beef heart mix + frozen brine shrimp/blood worms in a rotation.
