how can I make it happy again?

the mess I have now started as the most beautiful nanouk (i think) in this black self watering hanging pot, east window. it was bright purple and so happy, it was blooming and growing like crazy. then one day it started getting a lot of brown spots and the internet told me it was getting scorched from too much sun. it was exclusively bottom watered so wasn’t from water on the leaves. i moved it and it did okay for a bit, I tried to chop and prop cause it got leggy- when I put the cuttings directly in the soil they all died. take two propagating and the ones that grew in water ended up rotting when I put them in the soil. so current situation: -I have the one in the self watering white pot which isn’t that happy and has brown spots still, it was basically my only successful prop -I have the OG black pot with the sad survivors from my prop fails -I have 5-6 cuttings rooting in water that I also saved, they all look like this one

I want one big happy full plant lol I have a shallow planter I ordered coming in that I thought could work. it just seems like everything I do makes it worse. 😅
