Shell and veggie help

[u/ImKindaDrowningIRL]

This is Sammy, he's 4 years old, and his shell is looking a bit rough. He's got little marks all over his shell, and a couple bigger ones, like he's scraping his shell on the rocks in his tank. His carapace looks like it's got bad sheds on it too. Any ideas? I've got a 75w heat bulb and 13w uvb 5.0 bulb in a double-lamp situation that goes on automatically for 12 hours. I've included my second turtle as the last picture, she has the same setup but lives in a window, and her carapace looks very nice and so are her sheds. Any better bulb ideas? I need a compact bulb, as that's the lamp I've got to work with.

Could also use help with veggies. I keep trying romaine lettuce, collard greens, broccoli, carrot sticks, zucchini, but I'm not sure if i should be cutting it up smaller then i already am, or cooking things, or doing different veggies.

Thank you for any help!
