These articles explain how to supplement copper. Copper can be toxic to plants in excessive amounts, so only apply the required amounts:

Nickel is an essential nutrient for plants but is required in very small amounts. Supplementation with nickel is usually not needed, and excessive amounts are toxic to plants. However, if the soil pH is too high, plants can have trouble taking up nickel, so the recommended treatment is to lower the pH to the plant's ideal pH range:
