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.
