Where is
kosh? Ain't seen him for awhile.
Hope you're cool man.
I was the one having the sabbatical
But to your question
phat, i wouldn't be too worried (dependent on how far you reckon there is to go) sounds like she is herming slightly. You know the score, you've seen it before.
What it would make me question though is whether or not you have some slight stress factors in your garden (light leaks, temp etc) that need resolving or else maybe the GG has tendancies that way.
Not sure what the strainbase says so it might be worth checking over at OG to see if anyone has had any past GG experience and if so whether it has late flower herming tendancies.
Whatever happens happens ultimately but i guess best advice for now would be too pick flowers when you can spot them, check and recheck every aspect of your room for any problems and perhaps consider trying some different strains after all it could just be the GG not liking being indoors quite so much.
Good luck man.
You'll do good.
