Ordered her online, but she’s completely different from the plant I ordered. It looks like she might be a bromeliad but her leaves are thicker. Her main stem came damaged and started withering. I’m not sure if I should trim that part or leave it be. I’ve been watering whenever her soil a few inches down is dry, but recently the top part of the soil is turning almost grey. She also has a few tiny flies around her. Any help would be much appreciated!
