Need help with a leaf problem.

My problem is leaves on my plants start to turn a rusty orange color then curl up and die. It always starts with 2 fan leaves coming from the main stalk. Any help would be appreciated.

Anyone?

Nute burn maybe from watering or a deficiency more info needed for a better answer.

It's tough to determine without knowing what and how often you have been feeding etc.


This is a pic of calcium deficiency... is this how the problem started?
