Are young leafy sprouts just as bad.

I'm currently growing some collards, kale, and mustard greens for my RT. Since these are in the brassica family, I know they should be feed as part of a varied diet.
So does anyone know if the young sprouts contain the same level of nutrition as mature leaves? Also, Would anyone recommend that I could start using them to mix with the romaine that I feed him 3x a week? Is that too much intake from the brassica family of greens?
I'm currently waiting for my RT seed mix from Carolina pet supply. So that's why Ive been giving him the romaine. The other days he gets hibiscus flowers and leaves sprinked with moistend zoo med grassland tort food, but he does not eat the leaves. That's also sprinked on the romaine as well.

I don't know the nutrition levels but I do know that most torts in my experience prefer the young leaves/fresh sprouts of a plant by far!
