My edamame pods are beginning to get brown spots and eventually turning brown totally. A few days ago I pulled the plants with the most damage and removed the good pods But now the remaining plants are showing the same damage. I have seen a few squash bugs on them recently but I'm not sure if they are the ones doing the damage or if it is a disease of some sort. Anyone had this type of experience? Also wondering if it's too soon to go ahead and harvest the good pods. I have read they need to turn slightly yellow as a sign of it being time to harvest, but I'm afraid I'll lose the whole crop if I wait any longer.
