Hudson, reflecting on Tuesday's latest disappointment, told the Advertiser: "The first goal there was always going to be important but they got it and we capitulated a bit after that.
"When we go 1-0 down we've got to come up with something else because I think our heads go down too early.
"We don't seem to be able to come back from a goal down. We need to have strong minds and be strong as a team. That's what the manager wants.
Reflecting on the Blundell Park loss to Grimsby last Saturday, he added: "Our plan was to contain them in the first half but we were the better side and were a bit disappointed to come in at 0-0. Even though we didn't have many chances, possession wise we were better.
"They must have got a rollicking at half time. When we came out it seemed to be end to end but that's not the way we wanted to be playing. We wanted to contain them.
"We had a great chance before they scored and if that had gone in it might have been a different game.
"There's life in the bottom of the league yet. Everyone is fighting for their lives."
