Hey L. So, when you're talking orchids and you notice those bottom leaves getting all wrinkly and dehydrated-looking while the top ones are chillin' all nice and rigid, it's pretty common. Orchids are kinda drama queens when it comes to their leaves, especially after a repotting and trimming session. The plant's just focusing its energy on those fresh stems and flowers, so the bottom leaves might throw a bit of a tantrum and look under the weather. As long as those new stems and the top leaves are looking good and healthy, you're on the right track. Keep an eye on 'em, but don't sweat it too much!
