Hello, I have had an alocasia Regal Shield for two years and for the past few months, it has had problems with foliage. A year ago, this plant had larger leaves and produced more in the summer. This year, the leaves developed rusty brown (but not dry or crispy) areas on the edges of the leaves, that later had also yellow hue to them. The yellow would eventually spread across the leaf and it would die. Nothing like this had happened before. I am posting a photo of one of those leaves after it died off. The browning/yellowing issue seems to have slowed down now and the new leaves do not seem to be affected but there are hardly any new leaves growing. The newest one is tiny and almost white/transparent. Any idea what might be happening? Is it a nutrient deficiency? An infection? I will add that this plant did not go dormant last winter and is only kept indoors. It has been in the same spot for 2 years. It was repotted a few months back but the problem started before repotting.
