I sowed patio-container type tomatoes, think they might be tumbling toms. I have them on my window sill and they are growing strongly. This weekend they have started to develop white spots on some leaves. I want to find out what this is and how to stop it. I haven’t started feeding them yet, will start now. They are in quite a sunny spot.
The plants will soon recover but scald can happen if watering is neglected or too much heat is generated.
