Hi everyone,
I urgently need your help with a problem with some tomato Moneymaker plants growing in a growth chamber, under artificial light. In the last days, the leaves of all the plants have started to curl down manifestly. I also noticed that the stem of the plants has become quite thick. I would like to have your opinion on that. You can find a photo below
I am growing the tomato plants in 3.6 L pots, with a substrate (1:1:1 v/v/v) composed of 2 mm soil, quartz sand (0.8-1.2 mm) and vermiculite (< 2 mm). I water the plants every other day with 200 mL of half-strength Hoagland solution. Good growth of these plants is very important for me because they should be subjected to a later drought experiment.
Waiting for your reply,
thank you.

Niccolò Conti , Please check the temp and intensity of light given. As I can perceive from the image above temp or light intensity could be the main reason for the curling of leaves.
Thank you both for your quick reply and great help!
Kouadri Mohamed El Amine , the T° of the chamber is 25°C (day) and 18°C (night).
Ashwani Punia, I am checking the parameters of the light. I will let you know very soon.
Looking closer to the medium indicates that plants need simply more irrigation and water 💦
It seems due to insufficient light and low temperature. Please check these two parameters. Also, nutrient solution ph and EC.
Best
In order to arrive your problem , it seems that the temperature, light intensity and irrigation have to check rigourously. You have to establesh a good protocol concern the parameters you need.
Organise your work and good luck.
