Gravesend & Northfleet 1 Barnet 3
Title-chasing Barnet were the latest side to pick up three points from the Fleet when they came from behind to win 3-1 at Stonebridge Road.
"We are finding it hard to complete with the full-time teams," said Ford after the game.
"We may try to bring the players together on Monday morning with an extra training session. We are not keeping up with the Jones' at the moment."
Fleet threatened with two early Roy Essandoh headers, the first forcing Simon Clist into a goal-line clearance, before Bees keeper Scott Tynan's fingertips turned away another.
On 15 minutes Fleet took the lead, Manny Omoyinmi twisting into the box past four defenders before slipping the ball into the six-yard area where Barnet defender Ismail Yakubu knocked it over the goal-line past Tynan.
Barnet began to take control on the hour when a poor clearance from Chris Moore fell to Giuliano Grazioli to pick out Liam Hatch on the right wing and he slotted home beyond Fleet keeper James Pullen.
Within fiveminutes Barnet were in front, Hatch heading down to Nick Bailey who shot home from six yards.
The comeback was complete after 72 minutes when a cross from the right picked out Dean Sinclair, who drove the ball into the net at the near post from an acute angle.
