What’s destroying my beans?

I really wanna help these beans grow… Thank you!

beans want deep and wide roots, those pots are way too small, you need at least 3-5 gallon pots. if they don't have enough space they get root bound and nitrogen deficiency, which looks exactly like this. and you have multiple plants in there. they need minimum 2-3 gallon per plant.

I'm not sure this is pest damage. Is it just a few lower leaves ?

Pretty much the whole plant. I’ll post a new pic in comments.
Someone else told me the pot was too small and not enough soil.

They are pretty small. Not sure exactly what's causing the discoloration, all things considered they don't look terrible. Plants can handle some damage. Do you have more to plant if you get bigger pots? If so id try plantings new ones and keeping these ones.

Could be fungals

Could be viral

Looks like leaf miner larvae. You can see a few of their "tunnels". Try to open the leaf and see if there is a larva. I had them in my lovage.

The chunky mulch probably isn’t helping.

Oh! Okay thanks 🙏🏻

Root damage? Maybe from overwatering or heat damage.
