Once mature the fruit will not get bigger.

John is correct, if the fruit is still maturing, then the smaller fruit (which may have come from later flowers) will continue to mature and grow. Once they are ripe, however, that will be it. They will not grow larger. As Valencias are coming into season now (March through July), if your fruits are ripe now, then that is as bigs as they'll get. If they're still ripening, you might get a bit more size.

The freshly squeezed orange juice was wonderful this weekend: very sweet, with slightly tart aftertaste. Looking forward to even better juice week by week as they ripen even more, hopefully without fruit splitting or dropping (then splitting on impact)

Can't wait until next year as I read that small fruit are caused by poor irrigation the preceding year due to dried roots. I had neglected the tree for the last 2 years and just this year focused on the yard putting in drip irrigation, calculating ETo, fertilizing, and mulching the fruit trees.
