Does anyone know what's going on for this potato plant? The plants are still green (no indications of yellowing) but the stem is soft, the leaves are rolled and wilting while the surrounding plants look perfectly fine. Full disclosure, I am using urine to fertilize this container of potatoes as an experiment. This began 5 days ago after I had poured straight urine into the container. I've done this many times before with even more and there were no ill effects.
