This is the way I induce GW. Add a few jobes 15-15-15's to the water column
and wait a couple of days......pea soup.
It usually goes away as mysterious

This won't happen unless you do exclusively water column fertilization and
even the I doubt you'll see much effects as I personally have never seen it.
I have a UV on some tanks and it doesn't cause any problems.
Folks can squawk about till they are blue but the practical application of a
UV does little if any harm to the trace elements in a plant tank. They
certainly are not needed for a plant tank though. If you don't add much
Trace elements to begin with or some other thing like not doing water
changes etc well.......
A Magnum HOT and an 8 watt Aquanetics UV is all you'll need for GW and quick
clean up /polishing after a big replant etc. Run them together and you will
have no problems and they are both very easy/cheap to use. Tetra's new 5
watt UV is super BTW but cost about 80-90$ M.O.
Extremely well designed unit that is better for planted tank app's than
anything I've seen on the market.
BTW, use UV's on a timer.......your light timer. They do not need to be on
24/7 unless you have a GW bloom. Saves on bulb life/electric cost.
Generally they are temporary thing for a plant tank, not a long term one.

It is a reaction to lower lighting perhaps from overgrown areas maybe.
In high light tanks it never seems to get this. Same goes for Eichhornia
diversifolia. It is more sensitive even. Replanting sometimes if your rough
can hurt the plant.
See if the nice green parts are out in the light and unshaded and the
blackened parts are in the understory. A good trim and keeping it out in the
light should take care of things.
Can't finger a piscine suspect yet - but it
>sure looks fishy. Everything else in that tank grows super.
It's fast grower so if something's the matter it will show fast in this
plant also. Do the water change/trim/build back up the nutrients to good
levels and keep doing it until things are better.
Careful not to get to low of a NO3 level. Place in light more.
I would bet that would help about any plant:)
