Most likely a pH issue

Without more information all I can do is guess, I would say phosphorus deficiency here's a list of symptoms and a pic of the deficiencies progression

• Seen in lower and older leaves of the plant first
• Seen as Shiny/Dark that develop spotting and die
• Common sources of issues not enough Phosphorus when needed, or improper pH.
• leaves get bronze, purple or brown spots and splotches
• thick dry leaves die and become stiff and brittle
• stems sometimes turn bright red or purple, but not always
