Yeast Nutrient / Starter ?

[cyclonebeer]

I've got some washed yeast that i was planning to brew with next weekend. The yeast was washed and stored in January of this year. I bought some nutrient the other day (urea) and figured I'd add some to the 1 qt. starter. If its viable - great. If not, I've got a backup. How much nutrient should I add to the starter? I was thinking somewhere around 1/8 tsp.

Thats what I would use, I have a measuring spoon that says "just a pinch" that I use, I think its about 1/8tsp
