It is hard to tell from pictures, but it looks like you are watering the center of your pots from the center, water around the outside and the water will find the center of the pot.
Most growers don't say it but the first grows are always on the flop side unless they have an experienced partner or were a vegetable gardener previously. There is much to learn. If I had tomatoes growing out back I wouldn't study them everyday, but we do that with our plants in the basement or closet. We don't have to do something all the time or everyday. Just keep them watered as you get in a rhythm, you will learn when to water by lifting a pot.
The plants you germinated look good but I can't tell how tall they are, tall is not a necessity or always good, not indoors. The leaves look nice and healthy and you will have to "top" them and there are plenty of videos about it. A general rule of thumb is to top them when at 40% of the total growth you want. I think I have said before, I topped my plants wrong. The tops doubled but the plant went into a constant veg and grew into my lights and she just kept reaching and stretching.
Your lights are made to shine onto a specific area 3x3, 2x2 etc etc, the number of plants is not a factor. If your light draws 250w I think that should cover a 4x4. Check your watts if it is good for a 4x4 that is your tent size, you could grow as many has 5 plants in that and a lot of trimming will be required. I would work on their home for a few weeks and only water them.
