The quick answer is DME, if you have any on hand. Any other answer is going to require a lot more details. What are you mashing in? What sparge method? What temps? etc...

If thats your pre boil gravity expect it to finish close to your target of 1.050. If your pre boil target was 1.050 then just add some DME to your boil to reach your target OG. ErikH beat me to the punch --same answer.

You can add more grains next time, but you should really dig into why your efficieny is suffering if this is indeed the case. First place I'd look is grain crush. Second conversion check. Third process. Fourth pH. Other things can include but are not limited to faulty readings, reader error, equipment error/malfunction...etc...etc...etc.

Brew what you like. Do this, and you will find your inner brewer.

Could be any one (or combination) of many individual processes.

Give a run down of your:
Grain Bill
Water Used (volume)
Mash temps
Mash times


Basically, we need the "dear diary" narrative of what you did to get a lower-than-expected gravity.
