It looks like heat or light stress to me, but it's interesting that the other two are doing better. Temps looks fine in diary so excluding that...
Your soil could have been too hot for these lil babes. The curling at the edges are what said heat stress to me, and the light tip on new growth suggests overfeeding. Twisting and weird growth could be several things including feed/hot soil, pH, root problem, over or underwatering... I'd be more confident to say it was a root thing if the leaves were more yellow/spotted/decaying.
Did you spray them with anything with the lights on? Because that can also cause this kind of damage to such a young bean.
