As far as the drooping leafs.. That is most likely due to the over watering. My plants are great and my stems are purple from about 8" up into the entire stem system. It is usually due to new growth, plant genetics, and occasionally dramatic or extreme night temps. Purpling usually starts around 44 degrees F. If your temps dont get that low at night it is most likely due to new growth and genetics.
