My D adelae looks a little less 'perky' after the weather became hotter and drier the past few months. So I shifted it indoors and this is what became of the plant now

As you can see the larger plant has new leaves that are droopy (they are supposed to be erect during unfurling I suppose?) but they seem to be thin and wavy at the edges (dewing is still normal). Anyone have this problem? Please share and advise, much appreciated. Thanks!
