The leaves you're concerned about are the very early leaves.... not even the early FAN leaves.... this is normal, they're dying off and you can easily remove them just to "pretty-up" the plant (I'm a firm believer that plants actually like to LOOK pretty).... if you're talking about the light green on the tops, that's just new growth coming in and they'll darken - again, no worries.
Without a diary, it's hard to give you any other advice on your plant other than to say she looks good.
