Rice’s Copper Deficiency (Cu)

Activator of oxide-reduction enzymes. 

Deficiency – Younger leaves appear blue-green, becoming chlorotic near the tips. Chlorosis develops downwards along the midrib on both sides, followed by dark brown necrosis of the tips.

The leaves curl, maintaining the appearance of needles along their entire length or, occasionally, in the middle of the leaf, with the final base developing normally.
