Feeding and Nutrition :: can they eat too much veggies?

[Tilted]

my turtles finally have a healthy appetite they are still little, so I feed them twice a day, pellets in the morning and veggies in the pm. I was feeding them romaine lettuce, but they didn't eat any of it, so I switched over to collard greens, which they LOVE. But my question is can they eat too much of the greens?

Sometimes if they over eat veggies they can get the runs and it makes the tank rather messy.

I would vary the collard greens with some other leafy veggies---dandelions and red leaf lettuce, for example.
