Yes, Charles. This means the fruit will be dropping off. All citrus set more fruit than they can take to maturity. They drop excess fruit at 2 to 3 different stages. The first is the "BB" stage, which is what you currently seeing. They will also drop fruit if they don't get enough water, or if they get way too much water as well. You can actually touch those yellow fruit and they'll probably drop right off.
