Sometimes it is just a case of too much water, I have had some rot in 90F with almost 0 RH. My wife was watering while I was out of town and the plants just couldn't transpire all the water she was giving them. She thought they were dying and kept watering. The plant was soaking it up and couldn't get rid of it quick enough. Those only had a few days left and had been off nutes for 2 weeks, so she thought the yellowing leaves meant they needed more water.
