Hello. I have some small plants I am growing indoors. They are in a pretty cold room most of the time and there is little humidity. I live in Toronto.

Lately, I have been noticing a white powdery substance on the soil in several of the plants. The room is too cold and dry for fungus I think, but I cannot figure out what it is. The soil is a mixture of coconut coir and perlite.

I wonder if you can help with this and tell me what to do!

I am attaching pictures.

Thank you!

It looks like a fungus to me. You can use some cinnamon or a spray on fungicide to combat it. That little violet is suffering from the cold. Better find it a warmer home.

It could be salt deposits. Have you fertilized the plants? If you mixed up the coconut coir mix yourself, did you flush it through with water first?
