Please help! I have this plant which is very special to me (same age as my 6 years old child). I was away for 4 weeks, somebody would water it every week and I don't know what happened but is dying. Not sure if it was the weather (it was -20C average and the plant was close to the window so it could get sunlight, but inside the heat was set to 15C). Before I left the plant wasn't doing very good either. It had this layer on some leaves like dust and it looked dull. Right now it looks dry and I hav another 3 plants in the same situation. I know just how to water them so I feel lost and need to know if i can do something to save my plants, thx!
