What fertilizer product are you using, Ken?
Most of the fertilizers I use call for between a few drops and 1/4 teaspoon per gallon. I do have one jug of Peter's liquid root stimulator that asks for a 1/4 capful per 2 gallons, which is about 1 teaspoon per gallon. Primarily I use SUPERthrive on all of my young plants, fruits, veggies. That's one of the "a few drops per gallon" stuff.
Granted, I'm not a "guru" or anything, but I would never mix more than 1/2 strength for new trees (1/2 amount recommended in the instructions), and I would probably start with 1/4 strength dilution if using a product like MiracleGro.
EDIT - I just realized that Peter's isn't made anymore... and I also wanted to add that Al (tapla) always recommends to use fertilizers with 3:1:2 ratio when feeding figs, since this seems to be something that rarely comes up when talking about fertilizers.
