You write that it was in high heat. Just how high? Looks like heat stress to me. By looking at the pics, I don't think it's a nute deficiency right now. There could be a problem there, but it's probably high heat and maybe not quite enough water, although the soil looks like it might be wet. I think it's just heat. This will probably occur with your other plants if they stay in the heat.

Over the past 36 hours I have noticed one of the ladies take a turn for the worse, and quite rapidly at that. I can't figure out what would cause problems in such a rapid way, but the plant has been flushed, cooled (taken out of the high heat it was in), and is receiving what would be called "general supportive therapy" if it were a patient in a hospital (eg it is getting as much TLC as possible). Three days ago, this plant was thriving and a beautiful healthy green, no problems Rating: 5
