I have 4 newly planted citrus trees in my backyard. The two orange trees are doing well and have dark green foliage. The lime tree however is struggling with yellowing leaves all over. (Not just new growth and not with green veins- the whole leaf is uniformly yellow) They all get 10+ hours of sunlight in summer and are watered deeply once a week. Have used Dr Earth Fruit tree fertilizer for all of them. All of them are only a slight slope, it's possible the lime tree has slightly steeper slope but not by much. Any suggestions appreciated.
