sounds like your doing a great job, they certainly look the part for week 9.
seed firms always say 9 weeks often shapes out more like 12 especialy if your after some nice amber trichomes.
temps sound fantastic as for the higher humidity that's probably better at least directly after defoliation. run her till the trichomes look like what you want then drop the humidity to about 40/45% and no lower than 30/35% for the last day or two of her life she should get a little sticky.
these girls are in week 8 as of tomorrow they will get a light defoliation in the next few days then again more aggressively at week 10 when she starts getting clear water for 2 weeks.
