Here ill answer you with pictures and yes hydrotron.. hah ill ask around later for nutes.. but right now these look semi healthy right?.. and when you say i need a calcium source you mean calmag+? because im pretty sure there isnt a hydro store here so it might not be here on time if i ordered it... what happens without it?

When would you add more light? when the real leaves get little bigger? I can add two more CFL's or also MH or HPS whenever i just dont really know when hah
