Leaves and fruits falling off my citrus trees
I have a couple of small citrus trees (a lemon, lime, orange,kumquat and limequat). They are all in pots and the whole summer did well, because they were enjoying the sunny south side of the balcony. I moved them indoors in autumn (living room - constant 21°C) and since a while they have started to drop leaves and even the small fruits from the summer flowers. I watered them rarely indoors (once every 2-3 weeks). I used a couple of weeks ago 2-3 times a special liquid fertiliser. What is wrong with them ?

This is the natural process when the light gets reduced. They will go into a semi dormant state. The only way to prevent this will be to provide at least 200 watts of horticultural lighting for the plant. There are very many options available, but I am particular to LED lighting.
As long as you purchase a good LED from a reputable company, then it will be of a good quality, and will actually save on your energy bill while being much cooler to run. I use a brand called KIND LED myself, but these are top end, and will run quite expensive. There are many options available, but make sure to do the research when finding a good quality light for your citrus.
