Curly locks plant
I have had a curly locks plant for about a month now. The edges of the plant are turning black. I\\\'m not sure if I\\\'m overwatering or if the lighting is not right.
A Curly Locks Orchid Cactus does have some specifics in care and may show signs of stress if these needs are not met.
You may also want to use distilled water for your plant.
Here is a link with more information.
