I can't seem to find any info on this: is it normal for some lamb's ear leaves to turn yellow? I'm seeing both mature leaves and new leaves turning yellow, and having about 1 yellow leaf per day. The plant looks healthy overall and is having new growth.
I found a green aphid-looking insect on one of the stems today and killed it, but I couldn't find any more. I don't know if it is a concern.
Also thinking that because I'm keeping it inside (by a south window) it might not be getting as much sunlight as it would outside?
Soil is moist and fertilized with slow-release fertilizer a week ago.
On the very left of the image is a leaf half-turning yellow. I've removed the other yellow leaves that have dried up.
