Sticky lumpy bumpy leaves?

[Kevstar]

Hi guys,

Two of my Phals have sprouted new leaves but both of them are not like the dark green smooth feel of the previous leaves. They are lumpy and kind of Crispy? They don't look dead by any means but also don't look nice like the previous leaves.

Any idea what might cause this?

Couple of pics attached.

Thanks.

Kev.
