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.
