I received these small plants a while back, with plant dosing the leaves got massive..we're talking just as big as a lily pad. I wish I could post a photo...runners were several feet long and would always grow a lily pad like leaf (for a while I though a new plant would grow off them, but no such luck).
Even though the banana's browned beneath the monsterous leaves the plant continued to thrive...it ended up with leaves so big and red in color that I ended up giving it away because it was shading my other plants.
I assume the amazing growth was due to dosing and moderate-high lighting?
