What I’m looking for. The top buds tricromes are sufficiently Amber but the bottom buds are not close. I was thinking about chopping the top buds but that makes me nervous.
It’s common for the lower buds to mature slower than the upper. I do a staged harvest every grow.
I have never done it but many have done incremental harvests quite successfully. Good luck with it! 
So any harm in chopping the top buds off? Personal preference? Do you flush before a partial harvest then continue feeding afterwards?
No harm at all. Go for it.
It doesn’t really matter. All the plant is doing at this point is ripening flower.
So I can stop nutrients all together now?
