Moss turning yellow

I built this tank about 2 months ago. This would be my first attempt at an aquascape like this. Some of the moss on my trees are turning yellow. The moss is still growing but new growth is coming in yellow. It is producing what looks like seeds as well. I really don't have any experience in planted tanks so I'm seeking some advice.

Could be a number of things, nutrient deficiency/imbalance, weak lighting, too low of flow around the moss, probably more that I'm not thinking of. Can't tell from the photo, is that Java? What's your fert regimen? Parameters? Very interesting aquascape, btw.

Nothing good happens fast in an ecosystem.

The tank is a standard 75 gallon. Lighting are the popbloom freshwater turing 30's. There are 3 modules 100w each. I have the max set to 60% output. I paid for Christmas Moss but some of the cups came with Java on them. I think I have a little of both in the tank. Not really sure how to tell the difference. I do water changes with RODI water. Mix with Seachem: Equilibrium, Alkaline Buffer, Acid Buffer and Fresh Trace. PH:7 KH:6 Gh:8 temp 74. I use Seachem: Flourish, Flourish excel and Flourish Trace when doing water change. I am running an aquastation DC5000, 5000 liter pump at full speed to run the waterfalls. I am running a Jeabo DCP-2500 AT 13 watt setting that powers a spray bar at just under water surface level. I have China made CO2 reactor (Baking Soda & Citric Acid). It makes 40kg pressure. I have it set for 1 hrs before lights on and off. The drop checker just starts to change from blue to green but still on the blue side. I could turn up the volume of CO2 if needed. My bucephalandra seems like it is what I would call melting. Weird thing is it's sprouting new leaves in some spots as well. I am new to planted tanks so I at a loss here.

Piggy backing onto this thread. I ordered some Flame Moss online a few weeks ago. It was delayed en route and felt pretty warm on delivery. It's also sort of yellowish. Will it grow in eventually?

Discontinue the Excel. Excel does not play well with moss. If, after two weeks without Excel, the moss has not recovered, let us know.

What's the temperature?

I can't grow any kind of moss in my 78 degree planted Betta tank - they all turn yellow and die.

The same mosses do just fine in a bowl of plain water on a drafty chilly windowsill.

Go figure.

Sorry not the best picture I know, but just to show my Christmas moss in a tank that is always 27-28C (80-82F I think). It couldn't get any more lush and green! So I would say NOT a temp issue.

No CO2, cheap China led light, but using full Seachem fert's (except Excel and Advance) according to Seachem's suggested daily dosing schedule.
