My MG9 tends to have smaller calyxes up until week 11, then it really fattens up. Might be worth waiting.My Mountain Gold ladies are turning 10 weeks on Friday ... still debating on whether to chop or wait another week.
Took a tester last week and it definitely hits the spot
1 is pure bubblegum, another is bubblegum plus terpitine, and the 3rd is Fruity Fuel with a hint of bubblegum.
I let these ladies get too close to the lights (20" from 600w hps) so some stress on tops and dry(ish) resin but anything below canopy is like touching pine sap... they're that sticky.
Interesting foxtails on the head buds but couldn't get them to show up well in the pics.
That being said my MG11 is just fat calyxes all day long
