Very important, experienced growers advice needed!

Hello everyone. I'm creating this thread to inform you all of something very important that is happening to me. My grow seems to be failing! My beloved Purple Kush clone is dieing and I need anyone who really knows about hydroponic growing to go to this other thread on this same site to tell me what you think is going horribly wrong...
