# Hi everyone. I am struggling with severe curling and yellowing of my…

Hi everyone. I am struggling with severe curling and yellowing of my Grey Star. The plant below started out as two large pants which have died back to this one plant. I dont see any pests. I water the soil using a hygrometer. Humidity in the house is 35-45%. Temp is a steady 70.

Nothing i do seems to help. I repotted the plant and moved its location yesterday. It sits next to an east facing window. We have well water with a softener so i only use water from our reverse osmosis system.

However, the RO system has a calcite cartridge to help make the ro water less corrosive . Has anyone had trouble with using RO water with a calcite filter?

I use a general powder miracle grow frrtilizer that i dissolve in water every 3-4 waterings.

My next step is to test the RO water and switch fertilizers. I am lost at this point so i appreciate any help provided.

Needs more humidity.

And water when top inch of soil is dry. Don’t let it dry out all the way.

Ty. I will add a humidifier but my hygrometer says the soul is pretty moist. Does the picture look like it is too dry?

They don’t really like to dry out completely. Water when 2/3 dry. :) I use a chopstick to check.

The only way I’ve been able to keep my calatheas is a self watering pot and bottled water and yes a humidifier even then it struggles no matter wha type do.
