Top leaves starting to curl up

Looks like the beginning of an issue, any idea what this is? I have 3 plants and I take care of them all the same way, but this one is trying to tell me something. Overeating? Overeater?

Thanks for the help!

Is your RH all good ? Looks like its dry and the leaves are trying to catch some water, normally if your RH is too high your leaves will curl downwards
