Hi folks 🙂 i would really appreciate some help saving my rubber tree before it loses any leaves. There's still new growth but lots of it's leaves are getting spotty brown patches. It stays by a big south facing window and on top of a pebble tray and has been in that spot for 4 years and has doubled in size.
Really there could be a number of factors that have stressed it out. I was away for months with my family watering it sporadically. I just topped up the pot with 2 inches of compost. I watered it heavily once, potentially overwatered that time. I just turned the pot around so a different side is facing the sun. I misted it every day for about 5 days then read that's not necessary and stopped. I open the windows to get fresh air in. I watered it with the liquid i soaked dried beans in (not sure if that is bad or neutral). It also hasn't been repotted in years because i don't have a bigger pot.
All i can think to do is let it dry out completely, maybe move it away from the window in case it's sun burn and hope for the best. I've since trimmed off the really crispy bits so it looks less alarming. Any ideas please?
