Week 7.
I adjusted the watering system so that instead of 3 minutes twice a day, it now turns on at 5 hour intervals during the lights on period. So the first watering occurs at 8 am when the lights come on, then again at 1pm, 6pm and 11pm.*
This turned out to produce too much runoff after the first day. So I adjusted it down to 1 minute for each fertigation, still at the 5 hour intervals 4 times a day.
I started seeing trichomes on some of the buds. They are still very early in their development, but I can see some sugar leaves starting to get frosty. The smell, which is sweet and green, has become more prominent when the tent is open, but not overwhelming by any means.
