I've got an areca palm that's around 3 years old, and until the end of summer last year it was thriving.
Fed, watered and misted regularly over summer months, with watering reduced over winter months but misting maintained.
Summer 2018 it was thriving with lots of new growth, however around October time it took a big down turn, and the leaves started to turn and die as pictured below, and now my palm is about a third of the size it used to be.
There doesn't look to be any root rot, I can't find any pests/bugs on it, the soil has never been allowed to dry out, yet the sheer brightness of the yellow, the dark spots, and the lack of green in the leaves in the last picture has got me stumped. Any ideas?
