  • A yellowish halo separating the wholesome tissue at the middle of the leaf from the edges
  • Leaf edges curling below
  • Leaves twisting

While some or all of these signs will probably be current in a plant affected by nutrient burn, curling leaves are usually a sign of an overabundance of nitrogen, in particular.
