An update about my water lettuce (damn, I really prefer the German word for it; it translates to "shell flower") and the progress I've been making on it these past days, as well as the circumstances that lead to its current trouble:
Essentially, the water lettuce is really sensitive when it comes to touching other materials (glass, for example), and its leaves tend to get yellow-ish and eventually, gray, before they turn into some sort of mold and completely rot/melt away within some days if they get it contact with external things too much. It's somewhat hilarious, when you think about it, for an aquatic plant this fast-growing and efficient to be sensitive enough that it's just all "oh no, acid rain, guess i'm gonna shrivel away and turn into gray mold" whenever it touches water with its leaves, but whatever.
When I placed the water lettuce in my aquatic plant jar, some of its leaves turned yellow on the tips, and one shriveled away, but it wasn't too much, and the water lettuce even spread some offsprings. When I then changed the water some weeks later, however, large parts of it turned gray, and mold started to spread from its leaves' tips. I noticed that somewhat too late, but I moved the water lettuce and its offsprings to a new vessel when I noticed how severe it was, removed some of the clearly rotten leaves, and called it a day (picture one).
This turned out to not suffice, though, and two weeks later, it was in even worse condition (picture two).
So yesterday, I consequently cut off all the rotten or even slightly molded leaves from the water lettuces, threw away those of its offsprings that where gone too far, and moved the into separate jars, all of whom are high enough for their roots to extend to the fullest (which wasn't the case in the soup bowl it was in before) (picture 3).
The next morning (so this morning), I returned to see that many air bubbles had built in the new jars, which to me looks like a good sign since it's at least some sort of "activity" from the plant's side (picture 4)... some people told me that it's because of air between the roots and because of re-potting it, though 🤔
Anyways, if you know a thing or two about floating plants giving off air bubbles at their roots, don't hesitate to tell me what you think it is!!

So I asked on r/PlantedTank whether anyone could identify the type of mold that's growing on these leaves, and apparently, a mixture of different factors (too hot, too cold too little nutrients, not-dirty-enough-water etc.) can lead to this state. The yellow on the leaves is apparently common, although not to this extend. And the grayish stuff beneath the leaves' hairs is apparently how it looks when the plant starts feasting on its own leaves. The canon, in the end, appears to be that there is actually no mold on it, and that the plants are merely doing very poorly.
I'm starting to consider just putting them into our pond for the rest of summer, where they might hopefully get better or even multiply, since the closed-off small glasses seem to not go well with them, though I'm not sure if this will save them at this point 🤔
My personal mastodon instance, where I toot about whatever I find tootworthy. This instance's visual theme of trash and junk yards (you might have noticed the footer of the website, for example, which displays a junkyard) is inspired by the idea that "one person't trash is another person's treasure"; that people's ideas, thoughts and outcomes of hyperfixations can serve other people and inspire them, no matter how little they are, even if they didn't serve the one who had them in the first place. In a way, this instance is a garbage can of every thought I have and had and never used, as well as photos of things that never served beyond the moment (such as food) and things I do that don't serve anything (like having plants). If it's a thought or thing that I am weirdly proud of and it is mostly useless, it ends up here. Welcome to my junk yard! (There are also links to things I'm really proud of on my instance, though, as well as things that don't fit this categorization at all; it's not like everything consists of little things.)
