Correct, this looks perfectly normal and is all good. Those lighter coloured areas are just lacking pigmentation as the chlorophyll in the leaves in those areas have yet to have a chance of being completely "activated". Plant looks super healthy in general! Hope this helps... Organoman.
I would say by the look of that pic you have a nice healthy plant. New growth will be lighter green as the plant gets bigger sometimes. I would say nothing to be concerned about. Keep an eye on it maybe at the most. #trusttheplant cheers
