I’m fairly new to spider plants (though not plants in general), and I don’t seem to have the correct language to Google this!

I’m familiar with the floofy babies at the ends of runners. But what about new growth that develops in the elbows of runners and isn’t ‘terminal’ in the way babies are (that is, cutting them off would cut off the entire runner)?

Pic 1 is what I mean, and pic 2 has it highlighted. Pic 3 is the start of something similar - basically, what makes “point O” (the circled bit) different than the babies to the left? And what do I do when it gets really heavy?
