Soil help! I need to save my broccoli

So i've got 2 raised beds that i filled with a pretty dense clay like soil, i figured it would lack certain nutrients and restrict oxygen to the roots  so i added about 4 inches (12 inch deep beds) of FRESH cow manure mixed pretty well with hay and straw,, tilled and turned for a week or so, let it sit for a week or so and turned again, and layered the top with some good topsoil. I had well established broccoli plants (some cabbage too) and i needed to get them out of the house so i planted them the other day and they appear to be slightly stunted, and the leaves are curling inward slightly especcially on my cabbage. Could the leaves be cold temps and the stunting be from transplant? Or did i not give my manure enough time to age/compost? It has also been raining a lot, so theres a lot of variables, what should i do? How do i save my broccoli?

Hi Zak, welcome to Permies!

So there could be several things going on. Do you know where the fresh cow manure came from, what those cows ate whether it's fresh grass or hay and if that fresh grass or hay has been sprayed with herbicides? There are also soil borne diseases that can cause cabbage leaves to curl like fusarium and there is even a cabbage leaf curl virus (that's it's name). It could be related to just the fresh manure being too "hot" and not composted. There are a lot of variables. Where about on the globe are you and could you provide a picture?
