Leaves of young plant are becoming yellow
The leaves of my four week old Stress Killer are becoming yellow from the outside to the inside. I am a total beginner and I read that this may be overwatering, underwatering, overfeeding, underfeeding, so I am confused.

Any ideas what this could be?
Out of all 6, she’s the only one acting up. Transplanted her last sunday. Started seeing this around Tuesday. I do believe I overwatered on accident but all of my other girls are healthy. I’ve done nothing different between them

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
Ich habe 2 Pflanzen in Zelt und eine der Pflanze zeigt ziemliche Mängel. Viele Blätter sind mittlerweile gelb mit braunen Flecken. Die andere Pflanze hat diese Mängel aber nicht, beide wurden gleich gegossen, etc. Ich habe vor ein paar Tagen DolomitKalk und Worm Casting benutzt.
