I think I have a nitrogen deficiency. Help.

Here is a picture of my plant. They all look this way. Please any advise would be great. Thanks.

I think im also having a nitrogen defficiancy in my plant as well, but i cant tell in yours just because my plant is so different, but if your sure your plant has a nitrogen deff. you can take used coffe grounds and add as a top soil after watering/rain your plant that should take care of the nitrogen deff. fresh coffe grounds are usally too acidic. the used fresh coffe grounds will act as a slow-release of nitrogen for your plant. ive tryed it on my plant march 3rd. 2010 so hopefully when i wake up my older leafs yellowish/pale green color should be restored to a nice bright green. im not 100% on this though, i only read about 3 or 4 different articles about coffe grounds for plants and took a chance with it, so not to sure how this will turn out. ill let you know if my plant has anything different with it though or anything changes at all.
