I'm having some problems with my Moringa Oleifera. It's about 6 months old and is placed in a sunny window (oriented south), in southern Sweden. It's been growing well and looked healthy until recently.
Now, many of the leafs are getting spots, turning yellow and eventually falls of - see photo. Since it summer in Sweden now, I don't think it's lacking sunshine. Neither do I think it's gotten too little or too much water since I try to keep that under good control (letting it dry up, but not too long, before I water it).
Any ideas about what could be wrong?
