Kräuselnde blätter, verbrannte Sonnensegel spitzen, absterbende Blätter im unteren Bereich

i see only 1 problem - Ca deficiency that is why u have Claws

Could be to hot, like its root base, or to wet or not wet enough at the same time. But this is what it looks like when my plants get to warm in the roots. extra water normally helps but can water log em. also why white pots work well as they reflect a lot of this heat away.

I don't see dmg entirely but one of the simplest problems a plant can face that greatly disrupts osmosis is high ec, your tips are not showing the dmg yet I'd say medium sits around 1.5 ms/cm, Leaf curling downward taco is a sign of high ec disrupting osmosis coupled with possible slight oversaturation of medium. Early.

Hey, es ist leider etwas schwer aus einem Foto alles Infos herauszubekommen. Im Grunde kann es ein Zusammenspiel aus vielen Dingen sein. Temperatur, Luftfeuchtigkeit, Lichtintensität, Über- und Unterbewässerung, den pH-Wert und Nährstoffgehalt. Ich gehe stark davon aus, dass du zu oft gegossen hast, somit die Pflanze nich richtig atmen kann. Zudem könnte dein pH-Wer nicht stimmen, daher kann es zu einer Blockade im Substrat durch Salze kommmen. Checke dein gießverhalten und deinen pH-Wert, zudem ist weniger Dünger manchmal etwas besser.

Turgor pressure is compromised for some reason. Turgor is mostly generated through osmosis during transpiration. So something may be effecting the movement of water up and through the plant. Taco leaves hint at overwatering. This could be oversaturated medium. High Rh in the air. Plant isn't generating enough turgor to keep everything erect, she will slowly start choosing which part of leaf to reduce turgor so the more critical parts of the leaf can still remain efficent. 😉 Grow on!

Maybe something in root area. Pot exposed to sun, heats up and/or overdry too quick. No diary, hard to guess from one photo.
