I ignore curled leaves unless other symtoms appear b'c curled leaves are usually the result of various stresses, such as too hot or cold, too wet or dry, a heavy fruit burden, and it's also normal for quite a few hybrid varieties. And some varieties just curl more than others.

So I don't normally associate curled leaves with sick plants. When you say that plant has poor health, as compared to others, could you please describe what you mean?]

The plant seems to be a little more yellow colored than the others.

Perhaps too wet then. Yellowing of the leaves is the typical sign of too much water and too much water is a common cause of leaf roll. Try letting it dry out a bit more between watering. Soil doesn't always drain equally so sticking your finger deep into the soil is a better indicator of water needs. When in doubt, don't water. Plants will tolerate too little water better than too much.

Hope this helps.

Thanks. Will do. This one plant is not growing at the same rate as the others. I'll try the finger test and then decide.
