Just picked my first batch of green beans. Many of them look thin, not plump like normal. Is it perhaps the beans--blue lake and they are, of course, pole beans. They get plenty of water.

Blue Lake is an heirloom variety that produces a pod that is 5 to 6 inches.
Descriptions of this varieties characteristics include straight, plump and tender white seeds.
Environmental conditions could play a part in thin bean pods as well as watering and nutrients.
A garden journal is a great way to note the results from new varieties and a great resource to determine if you will choose those seeds again.
