meyer lemon will typically have fruit in many stages of maturity and will flower with fruit set. Dont worry if it decides to drop some of the smaller ones. That is perfectly normal and you dont need to do anything. Now if your focus is to let the tree grow then you need to remove all fruit once it has set and is the size of a marble.

A Meyer that size can hold quite a bit of fruit and still produce blossoms and more fruit. I would give it a little extra food, as it will need it; and I have found it nearly impossible to overfeed a Meyer when it is producing.

If you pinch off the blooms, the tree will just make more and cost it more energy; if you want to thin the fruit or cut off most of it, wait until the blooms are finished, then clip off the fruits.

Thanks, guys. Want to keep these lemons so more food it is! ;-)
