Any idea around when they started flowering or how old they are? What strain? They look like they are almost ready, but just about to start fattening up. I'm thinking if you cut now you might miss out on weight and quality. Probably 2-3 more weeks. Are you feeding it at all? They don't look like they are changing color at all like when fall comes around, you know what I mean... If you are feeding, maybe start cutting back and flushing?.... So they use up what they have and start to fade off...
