Make sure you check your ph and EC of the soil in that container before you waste another seed just to find out there was something wrong with your soil. Everything being equal, it should grow in there considering how good the other two look but obviously everything is not equal in this case. Something is wrong with that plant and the first thing I would check is pH, the second would be the EC of the soil. From the wrinkles in the leafs I would first assume pH but then looking at that one leaf on the right and the one facing us in the picture, the way those tips are bent down, it looks like very high N.
So, do yourself a favor and before you drop another bean, check that soil.
