It seems dying, maybe you can tell from leaves.
Temp between 18C - 25C

18 C when lights are off for 4 hrs, rest around 23-25C

All tomato plants shows same issues.

Its what happens when you mess with Mother Nature. Smiling Plants need more of the color spectrum to make chlorophyll. If I were you, I would turn off the colored lights and find some full spectrum lights. Also, tomatoes need 6 - 8 hours of darkness each night to complete the photosynthesis process.

Its hard to say. Turn off the colors and take a photo with natural light.

I grow tomatoes indoors with just a regular shop light and they do great.

I use fluorescent lights (4 per shelf) at around 5000K. That grows them well. Less light and they get leggy, more and they get a bit slightly burned on the leaves,

But when my current supply of 5000k bulbs wear out, I am going to LED tubes. They aren't much more expensive now, but apparently they last several years.

I would toss my fluorescents now, but I have them and they work great for a year. And after that, they work great as shop and kitchen lights.

But the LED tubes are probably the best deal in the future.
