Following his side's 4-0 Boxing Day thrashing of Hearts, Johnston was disappointed to leave Easter Road with nothing.
He said: "Hibs made it difficult, especially in the first half. They were right on top of the second balls.
"We knew the dangers they've got, scoring two goals from corners at Ross County.
"They had not been scoring a lot of goals recently. We knew that was going to be the danger.
"It's disappointing to lose a goal from a corner, especially with somebody getting a free header.
"It's disappointing and all the players are disappointed to lose such a soft goal to start with.
"I don't think there was much in it between the two teams and in the second half we dominated spells.
"At 1-0 you have to learn that you're still in the game and you cannot get caught on the counter-attack.
"We ended up getting beaten 3-0 and it looks like we have been thrashed when there was not much in the game."
