Fixing subject :)

It is highly probable that it does. The sun rises quit a few degrees south of east and give very little quality light to the tree. Even a south window would need more light. A west facing window is no different than an east one. Could you post a picture of your setup.

I have added some light (Future Harvest Development Sun Blaster 26W CFL 6400K Lighting )
Will it be sufficient? Tree lost a number of leaves and fruits before. Still sometimes I find lost leaf, but one green lemon is still there.

This is my setup. It worked wonders. My trees tripled in size over winter from the previous spring summer and fall.

She sits in the basement where my wife wont' complain. The ground level beet provide heat to the roots of my citrus trees above. Check out the video
