We added a new plant recently. I suspect that it started from there.

I read online that the ratio is 1:4, does that sound about right?

Thank you

Should I wait for the plants to get dry before I water it each time?

I checked for them and I did not see any. Thank you

No, it doesn’t get any direct sunlight. I was worried it wasn’t getting enough light in that spot, but I haven’t moved it yet
