Hi @adkandel,

From your photos, those beans do look like they’re becoming a bit distorted and stunted, which usually points to something stressing the plant rather than just a growth stage issue.

A few common causes to check for:

* Sap-sucking pests like aphids, mites or thrips. These can cause leaves to curl and new growth to come through misshapen. Have a close look under the leaves and along the stems.
* Environmental stress, especially inconsistent watering or sudden temperature swings, can lead to curling and poor development.
* Herbicide drift (even from nearby areas) can sometimes cause twisted, deformed growth if plants have been exposed.
* Nutrient imbalance, particularly a lack of key nutrients, can also affect leaf shape and growth.

If you do spot pests, a gentle treatment like

can help, making sure to get good coverage under the leaves.

Please let me know if you have any questions.
