I am new to dieffenbachias and wasn’t sure about care when I left for a few days a couple of weeks ago. I left my dieff in low light and when I got home, soil was dry, as expected, and my plant was dying :( I only have 1 south facing window in my room, as well as an artificial light I use during times when the sun isn’t really shining.

As you can tell from the photo, all leaves are starting to droop, some turning yellow, others getting brown on the edges.

Recently I have given him a smaller home in some fresh indoor plant soil and have watered him 1 time thoroughly.

Any tips on how to get this guy back to his best state?
