I have the same problem Valerie, I bought some Brussell Sprout plants from a local nursery about 10 days ago: they were outside on the benches and looked fine. I assumed they had been hardened off but symptoms now are as you describe. They should recover though. I will add a little Epsom Salts to the soil around the plants, that's one thing that really gives Brassicas a boost. Instructions say don't let ES touch the plant stems, just add a little to the soil around the plant, fork it in with a small trowel/fork and water in. Works wonders.
