Hi @spheraterra! Not really, the tomato gets enough sunlight. Every now and then I even have to roll the canopy out to protect it from so much heat. The problem must be another one, but I don't know what.

There are specific varieties of tomatoes adapted to pot cultivation. This one might not be one of them. They are very fragile and demanding plants.

You might be on to something! The rest of the plant looks good, but I'll keep an eye on it. It would be a pity if it dies! There are about 50 tomatoes hanging from it right now.
