Q.Snake Plant’s Curling Leaves
I have a snake plant, and I noticed recently that some of the leaves are curling and and buckling. I haven’t watered it in a couple weeks, and the soil is dry. I read it could be a thrips pest, but I can’t find photos of what that damage looks like. Maybe I’m underwatering? Since (I learned) it’s a type of succulent, is it showing me that it’s thirsty? I also just noticed that the tops of some of the leaves are cracking a bit, and the very top of the leaf on the left looks dead. Thank you!! Julie

It's difficult to see the issues you describe in the image. Since you mention the soil is completely dry; it would be time to water the plant. Though it stores moisture in it's leaves, if it is drawing on that water, it could result in the issues you are describing. Water when the soil is dry.

Thanks for the links, Downtoearthdigs, but the leaves aren't drooping, and the other link doesn't show what damage from thrips looks like, so I'm no closer to knowing what's wrong.
Obviously I didn't assume so, but could the curling and buckling shown be normal for these plants? Thanks!!

This can be an indicator of Thrips.
