Just bottled brown ale–I'm worried...

I just bottled a Moose Drool clone I got from my LBS and worried now that my FG is pretty far off it's target. It's supposed to be 1.014-1.015 and mine was at approx 1.020. I took the measurement after I added the 1.25 cups of bottling extract that was included in my kit.

I had it in the primary for 2 weeks and the secondary for 2 weeks. I thought it was pretty close to the correct FG when I racked it. Could the bottling malt cause such a spike?

Should I be worried about bottle bombs?

I'd be willing to bet it's the bottling solution you added. No worries

If you took the reading after you added the priming agent, that throws it off and will make it artificially higher.

Yeah, I figured it would make it a little higher with the bottling sugar added but do you think it would raise it that much?

The fermentation simply finished at 1.020 and Thisbe a common occurrence with all extract beers due to the fermentabity of the extract, pitch rate, aeration and fermentation temperature, as well as being a new brewer that hasn't gotten all the steps down and their importance in getting good attenuation.

Yes the priming solution through off the reading but 2 cups into 5 gallons is not moving the beer 5 Points

Don't worry about bottle bombs. If the yeast didn't ferment the sugar in the fermenter it isn't going to ferment it in the bottle.
