The fruits have started to pale and the leaves to curl. I'm pretty new to citrus.
Edit: Thanks to everyone! I'm going to try to make a couple of changes based on your suggestions.
Leaf curl on citrus usually means over watering. The fruit being lighter from nutrition problems.
How big is this tree, and what's your water and fertilizer schedule?
Overwatering is likely. I have it in an area where a rotating sprinkler runs once a day for an hour (I'm disabled and I rely on automation a lot). I'd like to set up a drip system, but I keep my citrus trees in pots.
I've only had this one since spring and I haven't fertilized it yet. I do have citrus fertilizer that I have used a couple of times a year on my yuzu, which is looking healthy. I keep the trees far enough apart that they shouldn't be able to infect each other if there's a disease. I can test the soil for nutrients.
It's a young tree, 2 1/2 to 3 ft tall.
Leaves curling up plus sunscald on the fruit.
You either moved it to a sunnier spot than it was used to or the temperature lately has been hotter than it is acclimatized to.
