I am going to sound like a snob but I do not know anyone who has grown mj from the light through a window (I don't confer other than here with alot of peopel who grow mj so this may not mean much) and you say the light is direct for 16 hours, can this be right? do you have a ppm meter? what kind of nutes, what is your ppm, have you thought about ro water? I guess there is alot to this other than switching methods, the main thing is to get yourself squared away so you can be smoking home grown asap
good luck
