In the next area, proceed up to a clump of weeds, stand in the center of it, and Cyclone all the weeds away to uncover a Mint on the ground. Proceed further upward and down a ladder, and lead yourself along the lower level of the floor until you get to a set of five weeds that, when Cycloned, reveal a puddle of water that is to be turned into an ice pillar with the Frost Psynergy. Climb back up and return near the entrance of the room, and go left to hop across the pillar. The set of six weeds above your position arranged in a circle, since they are arranged in a circle and only reveal puddles of water when cleared away, indicate that you are supposed to use the Reveal Psynergy here to expose and enter the stairwell into the next room.
