Sounds like a light or nutrient issue. How long are your lights on each day? Too much light can bleach plants, but too little and they won't thrive. Also, what's your phosphate level? Low phosphate can cause those brown spots.
Lights are on for 8 hours. I haven't checked phosphate, though. Gonna grab a test kit tomorrow.
Good call. Phosphate is often overlooked. If it's low, a little monopotassium phosphate can fix it fast. Just don't overdo it.

Another thing, how old are your plants? Older leaves naturally fade. If new growth looks good, it might just be natural shedding.

True, but if it's widespread, it's probably not just age. You got any algae issues? Sometimes plants lose vibrancy competing with algae for nutrients.

Algae's a good point. If you're seeing algae, cut back on light or ferts slightly. Balance is everything.

My two cents, try a blackout for a couple days. Sometimes plants bounce back after a reset. Worked for me once.

Before a blackout, maybe just reduce light intensity if your LEDs are dimmable. Less drastic and often just as effective.

Also, what's your water change routine? Fresh water brings in trace elements. If you're slacking, plants might be starving.
