Yellow leaf segments in Amorph. albus

From: StroWi at t-online.de (StroWi at t-online.de) on 2008.07.11 at 13:21:15(18134) Aroiders, would anyone know the cause of the symptoms shown here: http://www.bildercache.de/anzeige/20080711-111156-515.jpg This is a leaf from one offset of an Amorphophallus albus; the leaf was grown from one big tuber with several offsets, but only two offsets show the symtoms. +More This was a request from a member of the German Exoten-Forum; see: http://www.exoten-forum.de/vb/showthread.php?t#232&page0 post #297 I would not vote for a chimaera as it was suggested in the forum, but rather for a nutritional disorder or affected roots of that specific offset. It is remakable, too, that rather leaf segments further away from the first branching of the leaf are sowing the symptom, but not the leaf segments closer to the branchning. Any suggestions? Happy growing, Bernhard.

Sometimes the growths shoot up and expand so fast I think they may not be getting enough nitrogen. I supplement with a foliar spray. That being said, you should still keep an eye on the plant and isolate it from others. If the yellowing occurs on other leaves even after fertilization, or if the plant exhibits lack of vigor or distorted foliage consistently, discard it.
