What's your rescue routine when a plant starts dropping leaves and you can't diagnose it?
I've got a pothos and a fiddle suddenly shedding leaves and I can't figure out why. So far I've trimmed mushy bits, moved them out of direct sun, let the soil dry a bit, and poked around for pests but found nothing obvious. I tend to panic and either overwater or repot too fast. What do you actually do first when a plant starts dropping leaves with no clear culprit—quarantine, strip leaves, check roots, or wait it out and why?
