Hey man yeah looking around week 6 to me. You can crop her but you will lose some goodness better let her go another week at least before you start the flush :) Great looking plant btw. 👊 The main colas will mature quicker than the other buds due to having more light keep in mind to check various areas of said plant before making any drastic decisions :) Peace out .👌
It's really hard to tell from a picture. I do find that sometimes i can't make out the ambers unless i stare at it for a minute or so, allowing my eyes to adjust. Hope this helps.
That's a very clear picture 👍I would say there's no amber yet, I like to harvest when I start setting some Amber. I would begin flushing if you haven't yet.
