Like Diane R mentions, you could try reducing pellets some to see if that helps, but only if your rabbit continues eating hay really well. And how much pellets can be reduced will depend on the cut of hay you're feeding. Soft strands contain most of the nutrients, hard stems are mostly fiber. When a coarse hay is fed, more pellets need to be fed to make up for the lack of nutrients in the hay, to maintain a good protein/nutrient/fiber balance for good weight maintenance and health. But if a hay is soft to medium coarse, usually pellets can be reduced without causing weight loss or other health issues, because it's the right balance of protein, nutrients, and fiber for good health.
I've had to have some rabbits on a low or no pellet diet because of particular health issues, and they did perfectly fine with minimal to no pellets. But only because they were getting a cut of free fed grass hay(medium soft good quality green grass hay) that provided the necessary nutrients for weight and health maintenance, along with some select leafy greens.
As with any diet change, it's always important to monitor a rabbits weight and body condition to ensure they don't have unhealthy weight loss with the changes. So weighing and checking a rabbits body condition once or twice weekly is something I would suggest doing. And if in doubt or you have any concerns, it's always best to consult with a knowledgeable rabbit vet.

Another possible reason your rabbit isn't eating her cecotropes is because of the sudden diet change altering how the cecotropes taste to her. Because they smell and taste different and she's not used to that change yet, this could also be why she's leaving them. Once she gets used to them smelling different and has also had time to settle in, she may then start eating them again.
Along that line, the cilantro and parsley could also be affecting the smell and taste. So you may want to try cutting the parsley and cilantro first to see if that's the cause and if that doesn't resolve things, then try reducing pellet amounts. It may just be she has less need for vitamin packed pellets and needs more fiber from hay.
Monitoring weight and body condition, then tweeking the pellet, hay, and veggies in a rabbits diet, is how I've always worked out the best diet for each of my rabbits. What diet works best for one rabbit, may not be the same for another. So it can take a little bit of experimenting, but usually done gradually with slow changes, and always done as safely as possible for the health of the rabbit.
