Depends. What's the ppg of the "enhancer?" Does it give any sign of its sugar content?

And Abe above is correct. The best you can do now is calculate your OG. Thankfully, with extract, that's a pretty reliable process.

PPG? Pounds per gallon? No idea. Pack just says 1Kg Beer Enhancer Kit, ingredients spray dried malt and dextrose, direct 1:1 replacement for sugar addition.

Right. I slipped and forgot we were dealing with metric. I'm not gonna lie...I hate everything metric. But, I have many faults.

Anyway, ppg stands for points per gallon. It tells you how many gravity points you get when dissolving a known quantity of something in a gallon of water.

DME is generally around 40-42, of memory serves, and table sugar around 45. You can guess your enhancer is somewhere in the middle. So if you added roughly 2L water and 1kg of the enhancer, you added around 85 gravity points into nearly 20L water, so 85/5=17. That's 17 gravity points. So 1.025 + .017 = 1.042, which is your calculated OG after all additions. Seem good to you?

If fermentation has not started take a new OG measurement. Even if it has recently started it will be close.

Since you topped up I would not be confident with the first measurement, it is often difficult to get a good mix so you get either a false high or low reading, so all your additions will just be a guess.

At this point just RDWHAHB and wait for your beer to finish.

GuldTuborg,
That would be a victory if accurate, I think!
This sounds like a formula/principle I should learn.

Thanks all.

Default OG too low - can I raise?

Robert you are correct with my vague answer. (Wort gravity x wort volume including top off water) + (enhancer gravity x enhancer liquid volume) / 2 = OG

Like kh54s10 said, if you pitched within the last few hours (pending on yeast an lag time) than taking a gravity reading will be relatively accurate if the top off water was mixed well.

At this point though, kick back... Have a beer... And revel in the fact you'll have some more beer in 3 to 6 weeks.
