To me, it seems like you need to wait till those pistils are all orange.
My Heisenberg Special looks similar to yours but I am aiming towards day 65 to 70 for harvest.
By the way, they look gorgeous!!
Pistils being full orange means that THC is degrading in the flowers - which is why you chop at 50-60% trichrome maturity - FYI
Here is a silly graphic from 420mag... Not suggesting you go by this, but this is what I was referring to when talking about pistils
Here is a better graphic, with more accurate info for harvesting, however, I have noticed early onsight of cloudy trichombs on all of my Sour Stompers, my Heisenberg Special, and my Skyrone Stomper.
I was seeing nearly all cloudy around day 45 to 50 for those strains, but didn't have any amber until day 70~ for Skyrone and day 65 for the Sour Stompers... Additionally, the plants were clearly way to immature to harvest.
So, that is why I like to allow the calyx's to swell up and stop their growth, all while checking my trichomes.
