It looks like rot, are the plants receiving to much water? Is it around the base of the plants also? or just on the upper portions? If it is on the upper portions only, then you can go try applying something to it, If not then I would snap off any large portions that have the rot then apply a fungiside to the rest to help prevent spread. If it is rot from the bottom, then I would say the plant is probably dying.
