Did you harvest at 5 weeks???? If so then thats definately ur problem... Though the color of the trichs is the best way to judge harvest... it is sometimes hard for beginners and the impatience convinces you its done. I would say you could have let those girls for at least 3 more weeks. Alot of strains do most of their fattening up right towards the end. They also resin up too right at the end... The best way to judge harvest is 1) consider how long they have been flowering(minus 1 week from the time you change the light), most plants finish between 7-11 weeks 2)make sure approx. 70% of the trics are bigger than normal(like tiny dew drops) and milky with about 30% of them smaller and amber. 3) also make sure the individual calyxes(seedpods) are swelled with most of the hairs brown and very few new calyxes being made. I took me years to master harvesting at the right time... impatience is your enemy in this game...
