It might help for us to see a photo of it or at least know a bit more about how you're growing it. Is it a newly-rooted cutting? Is it getting at least 4-6 hours of full sun in summer? Did the inflo form buds, but the buds fell off?

Whenever they form an inflo (whether that inflo blooms or not), it will usually branch. You said it formed one last Fall, so now it's branching. In my limited experience, inflos fail to bloom for a number of reasons:

A) It's a newly-rooted cutting and the root system is not developed enough
B) Not enough sun
C) Insect infestation (spider mites)
D) Root damage and stress from over/underwatering.
E) Root system is overcrowded -- pot up to larger pot.
F) Also inflos that develop late in Fall don't usually bloom well indoors unless the plants are getting a lot of light and warmth.

So, take your pick!

Dave offers a good choice. Sometimes plants start inflos and then stop because it is late in the year. Also, a plant will produce an inflo when it is ready to flower. Your plant was a late bloomer and is not likely to show inflo growth until late June or July. Contrary to what you often read, plants do not all start to flower at the beginning of spring. I have a decade of flowering records on many of my plants and my flowering initiation (first flowers) where I live range for 5 months from may to September (although I may have some in April this year). The point is- be patient and care for your plant. It will flower when ready. In Texas and on the East Coast, flowering is already starting for some because the season is earlier. Bill

It branched with the inflo in August, and it has grew enough to branch again, it grew fast since August, and is branching again, it has grew 21" of new branch since August, I thought that it was growing too fast. It was a 1 tip in August and was 28" tall when it produced the inflo, and now it is a 5 tip and 20" taller. It was rooted when I got it, July 29 2007. It has grew 2' taller since I got it, its growth is just unbelievable, and it even stopped in winter for 4 months, and stopped for about a month because of the inflo, and if it didn't stop I thought it would grow too big for the house, I don't know where its getting all its growth from, I'm not using high nitrogen fertilizer . It gets about 8 hours of sun during summer, and since it is warming up now, I keep it out during the days, and in during the nights. I keep a full-spectrum florescent light on for 20 hours a day, and directly under the lights, while its in the house. It didn't produce any buds on the inflo. It has had scale for awhile, any I've been using insect sprays on it all winter, but the scale is not as bad now, but it doesn't got any other insects. I potted it in a bigger pot, and it lost some roots, and I used fertilizer, and superthive when I repotted it, but I used a moisture meter, to keep from overwatering, and underwatering, but in winter I didn't give it water unless it showed signs of needing it. Its roots was a little crowded, when I repotted it, about 2 weeks ago. It was outside when it produce that inflo in August, and it was a lot warmer than usual, lows was staying at about 70, and it was hot in August, the hottest month of 2007. It is not the same from August, that inflo is long gone, and now it is branching again, without no inflos at all, it branched in August, and now it is branching again, on different tips than in August.
