Was bedeuten diese vergilbten Blätter? Nährstoffmangel, Überdüngung, Abfall alter Blätter? Es sieht nicht nach Schädlingsbefall aus, die Blätter scheinen sauber zu sein.
Ich habe diesen seit Monaten aus einem winzigen Spross gezogen.
Es steht in einem Schrank unter Wachstumslampen, wahrscheinlich 400-500 FC / ~80-100 ppfd Licht für 16 Stunden, die Luftfeuchtigkeit liegt bei etwa 60-80 % (keine großen Schwankungen, die Luftfeuchtigkeit sinkt nur, wenn sich die Bewässerungszeit der Pflanzen nähert), und ich dünge mit Superthrive Foliage Pro bei fast jeder Bewässerung, die etwa alle etwa 10 Tage erfolgt. Wurzeln scheinen in Ordnung zu sein.
Hat jemand eine Idee, was es brauchen könnte?

It looks similar to underwatering to me. Is the soul very dry when you water it? Are the leaves very droopy and floppy when you water it? Does the soil seem to dry out quickly?
I have 3 adansonii variegatas and the same thing is happening. Soil is fine, water only when dry but not crispy dry. What I’ve noticed is the following (but idk if this makes sense just food for thought if anyone might chime in on that): I bought them all as baby plants and had them in a glass cabinet, nothing fancy with sealing or anything for humidity.. just protection from the cat. There I put a really cheap grow light in, it doesnt even say how many W it has, just full spectrum but it’s really small. When in there they grew and were fine, then I put them out when bigger under a sansi 450W full spectrum grow light and they started to yellow on the lower leaves and they fell off one by one. Roots were as fine as they can possibly be. Now back into the cabinet with the cheap grow light and no more yellowing.. I’m stumped and don’t understand it
