This is one issue I have been confused about. On Sensi Seeds website, it says that Skunk #1 is 35% Sativa and 65% Indica. Just by the way it is growing I know that is bullshit. Could they have inverted the numbers? Every other seed breeder with Skunk #1, The Pure, and Shit claims it to be 75% sativa - which seems correct based on my observations. So I suppose Sensi's info is wrong?

If they're at 71 days flowering, even adding 2 weeks to the flowering recommendation of Sensi puts you well past the safety zone for the plant to self-pollinate:
(according to the description on Sensi's website)
**Short flowering period (45 - 50 days)
Though that is a very short flowering period for a Sativa dominant plant.
Milky trich's are associated with head highs, like you would expect from a Sativa dominant plant.
Some have pushed similar plants to 90 and 100 days without amber showing.
But if it's self pollinating, it will only do so more as the days go by.
If you're satisfied with the yield it might just be time to chop to prevent more seeding.
