So I've made several mistakes while growing my tomato plants, and I'm still very new so bear with me. I'm concerned about the spots that keep forming on the leaves of the plants (only showing one plant). The spots seem to start at the bottom leaves and don't really form at the top leaves, although there is slight discoloration. After a day or so they also dry up and look almost burned or bleached. At first I thought that it was a deficiency? But it might also be overwatering? I've been misting the leaves which I just now learned isn't good. They are a potted variety that are only my balcony as long as it isn't too cold (which varies due to the weather in Sweden).
Another concern I have is the white spots in the soil, as shown here:
They weren't present as seedlings and look like small lumps of soil that have turned white. When touched they break into a washing powder consistency. Is it some sort of mold (overwatering?)
