Velvet Philodendron Leaves Curling & Turning Brown

Hello,
Please see photo attached. Not sure what plant this is? I’ve had this plant for 6 years, very healthy until last month.
Leaves are curling inwards, some are changing to red and falling off.
I’ve tried everything ( I think), changed soil, moved it to the sun, aired it outside, added Epsom salt for magnesium. I have a moisture thermostat and make sure not to over-water it.
I don’t know what else to do. Can you please help? Thank you!

Your plant is called a Velvet Philodendron (P. scandens f. micans) This type of philodendron plant has velvet-textured heart-shaped leaves that are greenish bronze with reddish brown undersides. Usually, if a Velvet Philodendron starts to turn brown and curl under, the plant is getting too much light and/or not enough water.

Check your Velvet Philodendron for spider mitesLearn how to identify and treat the plant pest called Spider Mites.. This houseplant pest could also be causing the problem.

A Heartleaf Philodendron is a fast growing plant that should be fed monthly in the spring and summer when it is actively producing new leaves. Fertilize a Velvet Philodendron every other month in the fall and winter with a basic houseplant food at 1/2 the recommended strength.
