Are these main colas ready for harvest ? I have no way of getting a magnifying class but i know they're pretty close . Please tell me what you think or how much longer i should let them go .
its all taste/high dependent but id say u got a week more on pic 2 and a good 2 weeks at least on pic 3, how long they been flowering for?
You don't need a magnifying glass, my friend. http://forum.grasscity.com/harvesting-processing-marijuana/666373-guide-when-harvest.html
You still got a couple weeks. Go to radio shack and get one. They're cheap. Or order one online. What strain?
Most Autos do not require a 12/12 photoperiod for growth. In my experience I've had the best results with 19/5.
you have about 3 weeks to go. stop adding nutrients, they are severely over fertilised. it stunts bud production. if I were you I would just use water from now on
