Strawberry Banana DWC

So I thought the yellowing was because she needed feeding, turns out it was the start of root rot, last grow I wanted to hang the plant whole so I got my buddy to saw through the trunk whilst I held the plant anyway he sawed through the net pot a bit, I didnt think anything of it as didnt look pierced but on closer inspection it was pierced and letting light in, she just hasn't developed to well and is tall and skinny and the 1st node just hasn't developed at all, I think I've fixed the issue now and she seems happier, new roots look good but they are underdeveloped but hopefully I can pull it back.
