No smell from buds at all

Friend when you see such things consider the followings 1. Burnt from the lighting? Your lights are very close, raise the lights 2. Burnt from the nutrients? Plenty pure water continiously, nutrients only after the plant recovery. 3. Maybe you use only poor soil that is only for clones or starting the seeds and it is not appropriate for growing plants? 4. Bad temperature, humidity and air flow in the grow room?
