Thanks so much for the replies! All the tips help in the journey for happy healthy plants!

Light source should be an inch or two from the top of the plants. Also repotting after the second leaves form and putting all but the top under ground helps make a thicker stem. Do this again at garden planting time and more roots grow from the buried stem. If they are way too tall maybe in the case where you are replanting due to weather or animal damage plant them horizontally underground taking care not the break the stem and they will do fine also. I usually have 75-150 plants per year grown from seed and planted in the garden. This saves a lot of money and I can have any variety I want. Currently planting Opalka for sauce, better boys, Cherokee purple and black krim for the table and sweet millions for treats for the chickens(cut in half).
I've been interested in the black krim tomatoes but not sure I'm experience enough for those fancy ones. But they sure look good in the seed catalogs!
I think I will try to put their leggy selves into the soil a little deeper and see if I get a stronger root system. I have heard of this before and didn't know if this would be a good stage for them or not. But I'm willing to try it!
The only great lighting source I use is the sunlight in the sun room, and my baby pumpkin plants have no complaints, but I can see that the tomatoes (who are summer lovers) would like a little more boost.
The one and only thing I've found specifically for tomato seedlings is a little sprinkle of powder milk in with the seed starting soil for a little calcium boost. Although with transplant time comes a wee bit closer I have read a couple of tricks.
Gelatin. Regular flavored gelatin (not the artificial sweetener ones) carefully put into the soil with hurting the root system and the burst of sugar feeds the micro organisms in the soil. I've also read you can grow seeds in gelatin for short time at the start. It's suppose be like science project for kids to watch the root system grow. I've never tried jello seed shooters
Baking soda. Also I've read that tomato plants love a little bit of baking soda in their water (2 tbsp per gallon of water), but this is also recommend for the transplant stage and beyond.
