Yellowing leaves on new autumn raspberry canes

NickyKB

I planted a row of polka autumn raspberries a few months ago only 3 of the 5 canes showed any signs of life but now 2 of them the new growth is starting to go yellow and look as though the plant is trying to fail. I put new compost and topsoil in along with some seaweed enhanced plant growth enhancer before I planted them. I've been watering them daily at the minute and have them some miracle gro a few days ago. Any idea what I can do to try and save them? I'm not an experienced gardener so any help would be appreciated. Thanks
