Pea Plants are Dying

I could be cut worms cutting the roots off. Look at the root, good luck.

Sounds like it might be calcium deficiency. The symptoms of calcium deficiency are more pronounced and appear earlier in most plants than if the soil is deficient in other elements. The symptoms are they lose their color and the plant dies prematurely. If that is the problem, adding small amounts of calcium to the water when you fertilize should correct the situation.
