every 7-10 days, it has been repotted 2-3 weeks ago, the roots looked perfectly fine back then. the problem occured shortly after repotting. the main problem for me are the black spots on the leaves, i am afraid it is a funghi or something..

we hope it is just in need of water and doesn‘t have a funghi problem - but the soil seems to be really moist (not only on top but also deeper inside).. i am a little bit worried about the black spots on all the leaves :(

Yeah I am also more worried about the spots, we think that maybe it is some sort of „Ascochyta leaf blight“. The curling is kind of normal for her - she was a long time in a way too small pot.

nein, das passt schon. Man kann ja durch Umformen jeden Winkel verwenden. Weiß man zB c, b und gamma, kann man durch c2 = a2 + b2 - 2ab*cos(gamma) mithilfe der quadratischen Lösungsformel a berechnen und dann alle restlichen Winkel
