Lupine Troubleshoot - help!

I potted up a few Lupins a month ago  it noticed some of the leaves have turned a funny grey colour.. do you guys think this could be some sort of fungal infection? 

All the leaves were green when I bought them in their little pots and this change of colour only started after I potted them up in a larger container.. have I done something wrong?

    The young new growth looks fine. Were they under cover or somewhere more sheltered before you potted them up in the current location? The shock of going from warm to cold could have caused the reddish colour. If so, they'll grow out of it. When you said grey I was expecting mildew or those nasty lupin aphids, but I don't see either.

    @JennyJ - you’re right, yes i kept some of them indoors and a couple on a sheltered spot outside before I moved them all to these larger containers in this more exposed spot.. I’m so glad they aren’t fungal infections phew! As you might have noticed a couple of them don’t seem to have as many of these reddish leaves on them and I suspect they have been the ones I left outside rather than indoors before I planted them out thus perhaps a lesser degree of shock.
