How much sunlight do they get? Fabaceae usually don't need extra nitrogen: in fact they are often used to fix atmospheric nitrogen in the ground. Yellowing usually means they don't get enough sunlight and/or the soil is waterlogged.
The top two get plenty of sunlight, although it has been raining a bit and they are in a 50/50 peat/leaf mulch mix.I was more concerned with the leaf wrinkling that they are showing and some of them have spots on the leaves.
The bottom one is in clay, i actually ended up pulling two of them. The roots were pretty compact, that soil is waterlogged and doesnt drain well. I planted them to hopefully open the soil up.
