Traverse the room while rolling on the thorns and avoiding the Samus Eaters. Roll from the first platform onto the thorns under the first set of Boyons. When just past the first Boyons, turn right and wait on the safe spot for a second to overload PLMs. Move right to touch the thorns and use that to damage boost leftwards onto the next thorns and roll into the third Samus Eater. Place a Power Bomb and then quickly unmorph and jump onto the block above and exit G-Mode before the Power Bomb explodes to break the wall. Note that if Samus is teleported into the Samus Eater when exiting G-Mode, then PLMs weren't properly overloaded before entering it. PLMs can be overloaded by waiting on their petals before entering them. Also note that there are much easier strats with more Energy or more Power Bombs.
