I need help figurine out what is wrong with these leaves

Hello,
it's the first time I try to grow something so I don't know a lot about gardening.
I have 3 Scarlet Runner beans plants that developed bumps on their first leaves.

A bit of a background:

• sprouted in a jiffy peat pod
• quickly transplanted to a small container with soil and composted manure
• Kept indoors with a grow light because the past few weeks were rainy with strong winds
• Plant are growing their first leaves, for some reason they have a super long stalk. around 5- 6 inches
• I started hardening them off yesterday, they spent an 1 hour in the shade
• I checked on the stalk, under the leaves and on the leaves but I don't see any pest
• Those seeds were given to me by an organism that promotes organic gardening in small space

From what I've read online, I think it could be the mosaic virus?
If this is the case I'm guessing the seeds I was given were tainted.

Thank you for your help

 

Any ideas?

 

I had a look at someone's very comprehensive "what is wrong with my bean plants" page, and didn't see a match to your issue here. I am hoping someone who grows beans and has first-hand knowledge will pipe up.

 

Can you share that page with me? I'd be interested in reading on what can go wrong with beans.

 

Sure thing! http://www.harvesttotable.com/2009/05/bean_growing_problems_troubles/

 

Thank you :)
