Yep, likely just started getting nice. They should be nearly fully chunked out by day 60 with the headband. Then it will go about a week finishing turning the pistils, and trichomes, and the rest of the calyxes that haven't expanded, will expand and.... bam you have ripe flowers ready for chop.
you'll open your tent around day 70 for chop and you'll be like, "awhh... now I have to chop em? .... when they look SO cool!?"
. It's weird chopping when it's all said and done, like by the time your getting the scissors out you have pretty much forgot you meant to smoke the shit instead of just look at it all year.
