relatively fast after buying them they got brown around the edges of the leaves. I increased humidity, but can't get much higher thanh 50%. I feel like putting them next to my plant lights encouraged new growth but the leaves still come out with brown edges. I water them weekly and fertilize bi-weekly since march. any ideas on which factors are most important to imrove for my 3 calatheas?

It might be the water you are using? Mine did that because I was using tap water to water it – they don’t like the minerals apparently – when I switched to filtered water it stopped getting worse and gradually the crispy bits regrew as green leaf
