My new setup ATS

I forgot yesterday to shoot a pic while I clean up and change pump.
the color is yellow in the middle and green at the edge of screen.

Well, that is usually too much light in the middle. Add iron, increase flow, or put a diffuser on the light.

If you cannot do these, then move the light back 10 cm. Last thing to try is 2 less hours light per day.

You shouldn't be lighting it 24/7 for a start, but Floyd has already mentioned that. Why do you have a timer if you leave the lights on all the time? Confused tbh.

Update:
removing the black coating on the walls of containers for better defusser.
