Dive into the acid to the left of the first floating platform to quickly drop down the room, holding left. Breaking spin may make the entry a bit easier to control; maintaining spin allows taking slightly less damage, because Samus reaches higher horizontal base speed when spinning. Use a flash suit to activate a diagonal shinespark after falling almost a screen below the large stalactite; Samus must spark relatively low because the acid physics makes the spark happens at a steeper angle.
