.005 gravity is 25 points of sugar on 5 gallons. Which sounds like a lot (about 1lb of 2row with typical conversion if I recall the references right, or about 1/2 lb of DME).
I'm guessing you won't notice a flavor or body difference. IF you are really concerned, get 1/2 lb of pale/light DME and add it in. But I'd personally not worry about it, unless you are making a beer that was 'light' ie target ABV of like <3% Then it might be important.
also a .005 gravity could be the difference of an extra bit of water, about 1/2 gallon I think (I've not worked the math)
