Visual Symptoms:
The leaves were lighter in appearance compared to control plants, and symptoms spread throughout the upper half of the foliage, especially around the growing tip and newly expanding leaves. Symptoms of Fe stress began as a slight marginal yellowing of the leaflets, especially around the base of the leaf. As symptomology progressed, the upper foliage displayed interveinal chlorosis on the new and expanding leaves, while the lower and mid foliage displayed a healthy dark green coloration (Cockson et al., 2019).
