You don’t identify the type of beans you’re growing, but generally speaking, if your beans seemed to be bursting out of their casing/pod, you waited too long to pick them. The beans come soon after the flowers and you have to check at least every other day to check their progress. Then, when the beans form, you can harvest at almost any time. (There are no hard and fast rules. Your seed packet sometimes gives a suggested mature size.) Small, 鈥渋mmature鈥 beans will be tender; older ones鈥攍ike those you picked鈥攏ot so much. They are still edible, though; you can just cook them a little longer.
As for the white coloration, that sounds like disease, possibly white mold. It’s not necessarily your fault, especially if your garden/area has experienced a lot of rain and temps have been cool. (You do not say where you are.) The plants may be a bit too close together, inhibiting air circulation, but the mold is due to rain, there’s not much you can do. Discard the plants and beans in trash, not compost.
