Hi! I have this Alocasia Frydek that has been growing really well, however I've noticed these small yellow dots/small areas of yellowing on a few leaves. It seems to be occurring on my older leaves. I've seen no signs of pests/bugs anywhere, but I did previously have a bout of spider mites on the plant. That was a few months ago, however, and was resolved.

I looked online, and some sources said that it might be due to inconsistent watering. I don't ever let the plant dry out, and I try to water thoroughly once a week. However, sometimes the days get away from me and I forget to water it, so it's not always consistently watered on the same day. Does anybody know if the little dots are watering issues, or a sign of another issue?

Other notes: the plant has grown a lot very quickly, so I didn't think there were any outstanding issues until I noticed the yellowing.
