TK- sorry to hear of your plight, but those don't look like tomatoes to me. I have been growing tomatoes for the last 3 years, and their leaves DO have serrations, not like those of Cannabis, but serrations none the less. I have no idea what those seedlings are. I have plants in my outdoor garden that I can not identify. Welcome to the Plant Kingdom! It's like really really big.
I've finished up to 3 girls under all CFL's and was pleased with the results. I now have a 400 HPS since I got a reflector, bulb and ballast for about $120 including shipping. I now have 3 girls flowering under this unit and they are only about 2+ weeks into 12/12. They are in soil and grown from seed. I think I got some feminzed seeds after a northern lights went hermi and started producing seeds.
