color change in my leaves
 

The leaves have never changed to this color before.

It's a DO mat gave 3 bunches this year.

Any ideas?

Looks like cold damage. What have your temps been like?

Looks normal to me for banana plants at this time of the year in SoCal.

Looks normal for So Cal. Bananas tend to reduce the number of leaves when the weather cools off (and they are entering dormancy) which may be some form of accelerated senescence in the older leaves.

The same affect happens if they are a bit underwatered or the humidity drops real low, which is also typical of So Cal this time of the year.
