Day 66 of Flower Super Silver Haze - close???

I am on day 66 of Flower things are going well. I only am using rainwater pH 6.5 PPM at 25

I can’t tell with the trichomes but was thinking go for 10weeks? Day 70? Harvest?

I don’t know how much more bulking up to expect.

Any thoughts? Super Silver Haze photo period from seed.
