pole lima beans
deformed and spotted bean
this is my first year with hydroponics. I planted lettuce and pole lima beans. Both grew fantastic! I use ebb and flow system with pvc tubing, growing outside. Time now to pick some of my many lima bean pods and many of the beans are rather deformed or even have some little yellowish spots on them, even tho there is no damage to see on the outside of the pod. I don't know what this is from; salts? too strong of nutrient mix? I use GH mixtures and my PH measure very good, a nice 6.0 right along. Any ideas? I took a picture of a bean because it is rather hard to describe. I appreciate any help, I have no one around here to ask...
