Adebayo Akinfenwa opened the scoring for the visitors midway through the first half and Paris Cowan-Hall made sure of the win with a second goal late on.
However, Jones refused to be over-critical of his young side and insisted that they could have had at least a share of the spoils if they had made better use of the ball in the final third.
“In the first half we suffered with one lapse in concentration but overall I felt we had enough chances and enough positions to do better and get an equaliser.
“Our final ball let us down; we got in to some great positions but shot over the bar or overhit a cross and they’re the problems we’ll keep on working on.
“When we got our best opportunity they just got in each other’s way but it’s frustrating because it wasn’t a bad performance – they just had more experience on the pitch and I think they used that.
“Where we are and the amount of players we’re working with, I can’t fault them. I get frustrated with a lot of things but we’ll change all that but it take a bit of time.
“We’ve been here six weeks and hopefully you can see the difference and what they’re trying to do.”
