LEDs diode layout feed back needed

[koko maung]

Hello LED expert,

I have zero knowledge in LED and spectrum. Can you guys please give me some feed back on my led layout? I am planning to change all of my leds in reefbreeder photon 24 because most of them are already burned out. My layout is a copy cat version of sb reef light but my circuit board only have 4 rows.

Thanks in advance!
