Personally I think the leaves that are kinda pale green yellow, are new growth that hasnt yet had the time to react with sunlight and produce cholorphyl.
With just a days even sunlight it will dissapear.
I think those exact leaves werent there when it went it to the dark.
The tips a mildy burned, but that is very common.
I think there fine and looking good and waiting for some strong sun/light.
Cheers.
