I rescued this plant and he was in a small pot with no drainage hole. When I moved him to a new bigger pot there were a ton of roots i had to break to get him out of the old pot. But he still had a lot healthy roots. Now that he is in the new pot, he's still getting these brown/ yellow spots. I cut off one of the bigger leaves that was nothing but a brown spot. Hes still getting new growth though. Ive tried watering more, watering less, more light, less light, and i dont see any pests on him. Please help me figure out how to make him happy.
