to answer the kush or chronic question u have, if you can tell the difference between chronic and kush then towardsw the end of flowering u will start to get some smell. i believe kush is more of a sweet smell, literally sweet.
i have a "Top44" in 4th week of flowering, sadly no buds on her yet but .. my night temps are getting around 12-13 degrees celcius which is 55-56 Farenheit , what do use think?
That is WAY too cold. During the day my temps max out at 27-28 degrees and at night it sits at around 20 (but doesnt go under 20). I needed to put a heater on a timer in there to keep it warm at night.
Cold temperatures are a sure fire way to make sure your plants grow painfully slowly.
