You're low on iron (+traces).
=========================
That may be but I was unable to find any liquid Iron safe for fish. I
suspected iron might be involved. I do add Ironite to the planted pond
plant's topsoil and they are always nice and green with lots of flowers. I
was hoping it would leach out into the water and some may be leaching -
because in the goldfish ponds they get a foot tall!!! The water lettuce
grows as big around as dinner plates. But in the 2000g koi pond they don't
do well at all. I'm definitely going to get some micronutrients before the
season begins in earnest here. I can't put out the floaters here until late
April so still have time.

Huh? It's all good. Even washers in the substrate will work. I do that too.

Do you think scattering the Ironite over the thick groups of pond plants
would do the trick? It has to dissolve in the water..... They encircle 2
1/2 sides of my pond and have all grown together into one monster clump.

You already dose iron in your tanks right? This is no different.

Yeah I got that. Water is water. The size and shape of the container
doesn't matter.
