What is wrong with it? Last time I had the same problem and it all died.. it was all going good until now!
Just added flourish and potassium…
If it is a nitrogen problem what can I do?

Thanks anyway... i think it is beacuse of macronutrients or i have moved it lately to a different spot?Not familiar with water lettuce ir a solution for your issue
the tips of the big root and the thin hairy rootCan you point out where it is melting?
Can you point out where it is melting?
Yeah calcium and magnesium was an issue but when I added crushed corals most calcium issues went awayWhat is your GH and KH? How much and how often do you change the water. Do you have a water quality report for your area? What does the report say or can you provide a link to it?
Typically when plants melt there is a nutrient deficiency in the water. I haven't seen root stunting in my tank. But according to this sight it might be a symptom of calcium deficiency.
One common problem with liquid fertilizers is that calcium and magnesium don't dissolve in water with a highly concentrated mix of other nutrients in the bottle. My experience in the past is with Flourish is that it doesn't have enough calcium and magnesium in it for my RO water tank. Many other fertilizers don't even have calcium and magnesium due to the solubility issue.
Typically calcium and magneisum is not an issue because tap water typically has a lot of it. But in some places the tap water may not have enough. Or you might not be doing enough water changes or are using RO water. The GH test specifically detects calcium and magnesium. And GH should be checked periodically. The GH level may change seasonally in some areas If your GH is low you could try using a GH booster such as Seachem equilibrium to increase GH. GH booster have calcium and magnesium and increaing GH by 2 degrees would be sufficient to resolve calcium deficiency
