Did I put enough fertilizer on my lawn?

I recently used 'Lawncare' rotary spreader to spread Scotts 29-3-4 Turf Builder. I don't have Scotts spreader so I went to the store and checked out the opening on Scotts spreader when it is at a 3.5 setting. I tried to match the area of the opening to my own spreader at home. I figured that if my spreader's opening was the same in size as the Scott's spreader, then walking at a steady pace should be enough. I read the package and for my lawn, 3000 sq ft., I should have used 9 lbs, but I don't think I used that much?....Shoud I add more? How would I know if I put too little or too much? It's a generic fertilizer (i.e. works on different species) and is intended for a late spring fertilization (May-June).

1. Better too little than too much. Weigh out what you need next time, and check that against what's being spread. Do you have a calendar of when to fertilize for the grass species you're growing? In much of the US, this is not the best time of year to be fertilizing.
2. bags of scotts fertilizers have the settings that most spreaders should be set on. you'll know if you put too much if the grass turns yellow and dies.
