Letting citrus bear when young is a bad idea, the trees just don't have the reserves in case there is a problem. Some will cite university studies that state the opposite but that is foolish. Homeowners seldom give the trees the expert planting and care that trained horticulture experts do.

I'm in Florida also and some parts of the state have been dry like here but other spots have been drenched. What has it been like where you live? Have you fertilized the tree? How deep did you plant the tree? With citrus you should be able to just see the tops of the roots at the trunk. Is the tree mulched? When you planted the tree did you just put it in the sand or did you amend the soil? Amending the soil and heavy rains that last for days is a recipe for disaster and is why on our sand the soil should not be amended. Just need some more details.
