How many hours/day do you run the lights? I would guess the issue is too much light from the way that looks. Cut your lighting period back.

I run it 24-7

I run it 24-7

Cut it back to 18 hrs/day. That will help illuminate that center white area

You need more light, or more often cleaning. What is happening is that the light is weak and causing dark growth in high nutrient water (high nutrients need more light to grow green), and so the dark growth is blocking flow and light, and dying and letting go. Go 24 hours light, and clean as soon as the screen fills up. Then if it continues for weeks, you could try stronger lights, preferrable all red 660nm, which is what algae uses most.
