Roll through the item to overload PLMs, then go down through the speed blocks and exit G-mode to collect the item. Note that if the item has already been collected, Samus can overload PLMs with Grapple.

With Morph and Grapple, quickly grapple to then release grapple on the grapple blocks a few times until they stop working. Be careful not to fall into the spikes.

  "comeInWithGMode": {
    "mode": "direct",
