Stretchier plants have a lower transpiration rate, then the healthier plants with tighter nodes. She's rootbound? That shouldn't be to much of a problem, as woody mentioned. Especially if you have limited space. Bonzai her, and maybe run a water dep test to see how often she's thristy. Water then wait for the lowest fan leaves to droop, then log the amount of time. Plants can handle drought like conditions, better than they can being waterlogged. Ph your next plain watering before you pour, then test the runoff. For soil 6.8 +/- .3 is the butter zone. If the runoof is too high or low, you'll want to correct the difference next time you feed/water. My 2 pesos.
