I Have a Meyer Lemon Tree Potted Indoors for Winter
It is flowering and the flowers are falling off. I have a plant light on it for 8 hrs a day and I water according to a moisture meter but the leaves are still turning yellow and are cupped. What am I doing wrong and will I still get fruit? Any help would be appreciated. Thanks, Michael from NY

Most citrus have many more blooms than the plant could ever support if pollinated. In fact, a lot of immature fruits often fall off because the plant can't support the blooms that did get pollinated. This is a normal, self-preservation trait.
If the leaves are turning yellow, are you feeding a well balanced or cirtus food acccording to package directions? And, I've found a moisture meter all but useless. I prefer to check soil moisture with my fingertips about 4" down, or by "weight".
