I don't think it's over watered. I water only to the size of the plant. I wait until the soil is completely dry, but not too dry. I am using 20-20-20 nutrients. Yeah, I guess there is no textbook way of watering, except not too much and only when they need it. here are some small pictures. You can't really tell much by how small they are, and b/c of the hps light. My new camera will be here soon!
