I have had this beautiful plant for almost a year and it has been perfect. I repotted it a couple weeks ago and a week later it got cold so I brought all my plants in and I checked on them to water them and noticed this one looked bad. I look at my plants all the time like they are my babies it's like this happened overnight so fast I don't understand and can't find answers thru google. I'm so sad I don't know what happened all of a sudden. I gave it water and now that it's nice again it's back in the sun outside. All I can do is post pictures to describe please help.

I think that this plant prefers indirect sun rather than direct sun. The plant is next to a big window in that photo. Perhaps it needs to be moved so that it doesn't get scorched. White or yellow leaves could be an indicator of too much sun for this plant. I can't say for sure that this is the cause, but it is something to consider.

It does look like sunburn. If the plant was in a shadier spot and moved to more light that could do it. It would need to be gradually introduced to more light.

Sun burn. That plant will do good if you keep it outside in the shade.
