Not sure you can save it, but you can try. The pot looks small for the size of the plant. When you water it, do you water thoroughly, letting the excess water drain completely before returning it to the cachepot? These plants do like water and will tell you they are thirsty by droopy leaves, but the pot must drain thoroughly.

Here's what I would do: clip off all broken and dried up leaves. Get a slightly larger pot (or use the same one if it still seems roomy enough for the roots) and fresh potting mix. Very gently remove the old potting mix from the roots and repot with the fresh mix. Water well and keep it in shade to see if leaves perk up. It won't take long before you see some change in the leaves if they aren't too far gone.

looks severely sunburned ...

i would tip it out of the pot.. and look at the roots ... if rotted.. be done with it ...

if active with new growth ... i would put it back in the pot.. and water properly for a month or 3.. and see if new leaves appear ... any leaf with green can still process light into energy ... and i would only cut one off for each new one that emerges ..

if in 2 or 3 months.. its settled down.. destressed.. i would repot it as suggested above ... i dont like to heap stress upon stress .. lets deal with one at a time ...

if you want to go thru all that.. or any derivation therein ... just to see if you can save it.. go for it.. but if its going to piss you off every time you look at it.. just be done with it.. and move on to a new plant ....

Thanks heaps for the suggestions guys. I’ll definitely give it a try. I normally only water it when the leaves look a bit droopy and the plant grew pretty well in the past. it has only started becoming like this in the past six months and i didnt do anything differently thats why i find it weird and dont know what caused the plant to become like this and moving it to the balcony probably makes it worse due to the sunlight.

i checked the root and it seems not rotten? do you guys think it‘s rootbound?
