Unmorph on the leftmost edge of the Speed blocks and jump across. Landing on the right side Speedblock, and the solid tile, gives enough time to run to the item and fall before the block respawns. Or jump fully over the Speed blocks and turn around using X-Ray after collecting the item.

Stand on the farthest pixel into the door possible using moonwalk, X-Ray, or morphball turn around. Run towards the water and jump on the last possible frame. Perform the CWJ off of the item pedestal to cross to the other side.

It's not even necessary to jump through the door, the in-room doorsill gives enough running room to make it up.

In direct g-mode, the door will not close, and the in-room doorsill gives enough running room to make it up to the invisible ledge.

Run then do a very small spin jump to clip into the left side of the first gate. While inside the gate, back up to get the maximum run distance using either Moonwalk or X-Ray Turnaround and repeat for the next gate. It is also possible to clip into the gates by aiming down while in the spin jump. A down-back is also possible for clipping into the first gate, but it is generally harder.

The only way the Wavers will get to the door is if the right crumble blocks are all broken. This assumes that Samus comes from the left with Speed, a mockball, or a crouch gate clip. After the crumbles are broken, shoot the ceiling block and wait by the door for the Waver to come. Note that if Samus takes more than 35 seconds after entering the room, before shooting the ceiling, the Waver will not come down.

Freeze a small hopper to the side and kill the remaining Side Hoppers. Stand against the left wall (damage knockback will align Samus with the wall) and shoot up to freeze the hopper. Jump up to land on it, aligned with the wall. Alternatively, Jump and shoot down to freeze the hopper as a way to avoid damage. Fire a Super just above the door shell to hit the Gate.

Jump to the door leading to X-Ray either by jumping from spikes or with a very precise jump. Cross the room by Jumping atop the spikes. Taking enemy damage can be used to reduce some spike damage. The final jump can either be made by jumping from the bottommost spike stair or from the safe stair. Setup run speed atop the spike stair by holding forward to be pushed backward. The safe stair jump is much harder, but can be made without every pixel of runway.
