My Kalanchoe leaves changed to oak leaf type

[Dong]

My Kalanchoe leaves has changed the ovate shape to oak leaf type. Normally Kalanchoe's leaves have ovate shape with crenate margins. Now their leaves become narrow, and the crenate margins become bigger.

My questions are
1. Is this an viaration or the plant was not cared in correct way?
2. If the leaves will change back and how?

You can check the photos between normal Kalanchoe' leaf and my plant's leaf.

Have a look here please! Don't think they will change back. Your plant is actually very healthy and its leaves look lovely.

Hi Alp. Thanks for your reply. I still love my Kalanchoe even if its leaves will not change back. I need to care more about it to make it bloom well. It has few flowers since last year.
