I was just about to order the Agromax Window Tent "Mother Keeper" for my bonsai's mothers and figured i look up some reviews for their tents. But i'm going to order it anyways seeing as how more than likely the OP of this thread was just a troll :D
It seems like its just your lights could be to close, but people have used 600w at 2 weeks so I don't know. Just try lifting the light to about 18inch/45cm and that might help. If that doesn't fix it then its either your nutrients or your fingernail polish :wink:
