Rattlesnake

Dry spots on Rattlesnake Calathea leaves - cause?

Fertilizer- as in liquid, pellets, or soil?

crispy plant

at what point do i give it the big chop

Can’t tell if she’s dying or not

How do I make sure she doesn’t die? I feel like her leaves aren’t as vibrant as they were when I got her. I didn’t get a picture of her root system but it was pretty full so I moved her to a new pot recently. This one has a mix of orchid bark, perlite and soil, but a little more heavy on the orchard bark since I was reading that this one needs a bit more airflow in the soil. I’m concerned about the color of the stems and such. I’ve attached some photos for reference. Any tips or suggestions for her?
