My Fiddle Leaf is in the corner of my north facing living room and gets dappled sunlight throughout the day. The leaves were at first just turning light brown around the edges (past year). But now they are getting dark brown spots as well. For the first time in a year he had some new growth (see bottom of tree) just a couple months ago these leaves sprouted. But the top leaves are all diseased 🙁 what can I do for him? Repotting? More water? Less water? Please help!
