Is it ready to harvest?

that bud looks very small from that pic.

can you take a pic more zoomed out?
Best way to tell if she ready is use a loupe and look at the trichomes on the bud,
clear is not ready
milky can be harvested
some amber is perfect

if you have no loupe. download a magnifier app on your phone

No

No, more calyx swell and brown.pistils needed yet.
