After looking at the pics,looks as if you picked to early.Always use a 60x-100x scope to check the maturation of the trichomes (I like 100% cloudy/milky or 90% cloudy/milky 10% amber....amber color signifies the trichomes have reached peak maturity and that the THC has degraded and converted to CBD...hence why I like 100% cloudy/milky or 90% cloudy/miljy 10% amber.
Also another sign other than just trichome maturation is swelling of the calyxes and a darker reddening of the hairs from a light orange to a darker orange/red aswell as the hairs receeding way back into the calyxes.
You'll get the swing of it,just takes time,dedication,and more runs under your belt.If I can help in any way,just LMK bro.
