Thanks for the info - I was afraid that 3 leaves meant it was a male.

Even if it is a male, the seedlings are only about 2 weeks behind the older plant. I'm limiting myself to 3 plants for final growing because of space and a busy schedule. Eventually, I'll have to trim the plants or stunt their growth somehow because they only have a few feet to grow. But I'll cross that bridge when I get to it. Each plant will have it's own little skylight so it's almost like an artificial growroom. Soon I'll be painting the area around the skylights white so they will be nice and bright even during the fall. There's ventilation coming from 3 directions and fresh air right under the plants.

Right now they're getting weak doses of MiracleGro for Tomatoes but I need to start giving them some real stuff soon. Could someone suggest a good veg nutrient for a soil/sunlight indoor plant?
