Dosage for generic yeast nutrient?

Someone left a little jar of Crosby-Baker brand yeast nutrient in a drawer in my kitchen. It’s a DAP/urea blend, and the instructions printed on it say to use 1 tsp/gal. I’m thinking that’s for wine and would be serious overkill for an all-malt wort. Anyone have a recommended dosage for brewing? I’m thinking maybe 3 g for a 6 gal batch.

I go for about 1tsp per 5 gal (I normally put in 2 tsp for a 12 gal batch).  The nutrients with DAP are definitely noticeable in beer if you overuse them.

I want to say 1tsp per 5 gal is what my little jar of nutrient said when I used it two weeks ago.

One of the few times I’ve remembered to use it.  I just can’t recall if I put it in both batches, or only one.
