Nutrient deficiency. What fertiliser do you use? For container trees, I use a slow release citrus fert once per year then a liquid feed every couple of months.

Maybe I ask which brand of fertilizers do you use? I used the 5-5-5 organic one.

Give it Ironite fertilizer..... it needs more iron! That what I do when my citrus start looking a bit yellow.

This is it!

Thank you. 🙂
