Yellowing runner beans

Hello,

Am new to the forum, myself and my wife recently started on our first allotment - hard work but very rewarding (long way to go yet though..heh)

I have a question I was hoping to get some help with though - we were given some runner bean plants from my father in law, they were growing in seed trays. We've planted them at the allotment (with a wigwam for support), however since planting them the foliage has turned a very light green/yellow colour, and they don't seem to be growing much. Apologies if it's a bit of a newbie question but any ideas what the problem may be? They've been receiving plenty of water and light (no shade) however it's quite a windy site...

Any advice would be appreciated

Thanks for the advice - thought the wind might be an issue, although we have some broad bean plants growing nearby which seem to be fine. Will give it time and see how they go, might try and create some shelter for them too.

Thanks again
