Rescued this fiddle leaf from the grocery store i already trimmed 3 leaves closer to the bottom that were about 50% brown
Looking for advice and tips on soil, lighting, watering, pruning all of the things
Roots are growing out the bottom tips and advice on repotting?
Give me everything you got on this plant

My plant was doing so good while shoved into a super tiny pot with 2 other succulents, i repotted them all seperately and this one started drooping its been sitting under a light for about a month now and its only getting worse
Tips and advice please
