The fact that a leaf leans over does not mean your plant is not up taking water. Monstera is a climbing plant. If seeds do not germinate up in the canopy in a host plant, but on the ground (as is the habit of houseplant containerized Monstera) it will crawl across the ground until it finds something to climb. 'Leaning' leaves might be more a function of too little light instead of inability to uptake water
