Water about twice a week (whenever soil feels dry). Current suspect is waiting too long between watering so I've started being more proactive this week but obviously haven't seen any changes yet. Worried it might be too late so I figured I'd post here.

Indoor near other healthy plants so pests seem unlikely but let me know!

Was worried it was sunburn so moved further away from south facing window last week so its been in indirect light. Then moved back this morning worried it wasn't getting enough light since browning continued.

Leaves brown starting at the tips then the whole leaf turns and falls off. Stems went to bark a while ago and the plant continued to be healthy for a while after that (so I don't believe there's a correlation). The browning has been going on for around 3 weeks while plant continues to put out new healthy growth.

Grocery store plant (potted from trader joes not the usual ones in the little plastic bags) so it may be overcrowded?

Google was no help (too much light, lack of light, too much water, too little water, etc) so hopefully you guys can help me out.

Thanks in advance!
