I have 3 small, very nice, green citrus trees about 2 feet tall under lights in my basement. I brought them inside in September from the garden and they growing nice. I would like to know what (type, brand and where to get) fertilizer and how much should I use. I have not fertilized them yet, but nice and green with no blossoms.

A balanced fertilizer like 10-10-10 or 20-20-20 will be fine. Follow the directions on the package when applying, simply because different manufactures have different application directions. Most home and garden centers will carry them. If possible, find a citrus fertilizer (you should be able to find them at garden nurseries) which will also make sure that micro nutrients are supplied.
