Hii I need help with my fiddle plant called riddle! She’s losing leaves every time I water her and I just try to mist the top of the soil. She has a East window next to her but she’s in the corner so the sun doesn’t hit her directly and across the room there’s a south window but still no direct sun. She grows leaves at the bottom but not the top. And sometimes she gets some browning tips. Should I change soil?
