Chlorosis? (growing, leaves, yellowing, water)

[TheHurricaneKid]

One of my three mangoes have had chlorosis for a while now and even when it didn't it's leaves were a more anemic green than that of other mangoes. Weird thing is, the other two mangoes do just fine, and so do other mangoes in the area. It's not the soil, since there are many mango cultivars growing here and they have the typical dark green mango leaves.

What other causes of chlorosis is there besides insufficient iron in soil?

Low nitrogen or low magnesium or low sulphur will also cause yellowing. The other possible cause is too much water.
