Sorry i was surfing today ^^
These two posts can give you an idea i think.
Now on your synchro i’ve bad news. Your actual low density of light don’t permit to reach a “normalized” maturity of your plant, i say that only by the development of your bud on the first pic. Trichome’s spanlife will not corroborate with your flowers development this way.
I mean by that than you will smoke immature flowers, and than the visible trichomes are only a part of what we can consider as the potency. It’s polemic for the moment (like also things proven since centuries lol, we stay stoners ^^), but terpens too play a role.
I don’t judge your way at all, but if you want to let enough time to your flowers to age in same time of your trichomes you have to change a bit your strategy. Like to grow shorter plants than you don’t let stretch too much. This way they will have less sites (flowers) to furnish and can concentrate their forces.
For partial harvest, it’s used since decades specially in greenhouses. Nothing to worry about at the moment you protect the trunk freshly cutted. Using wax give a good security, but it’s not critical.
hop it help, have a nice cone ! I like the GDP, it transform me in a rooted plant lol but without hammering the body and the brain. Make me contemplative ^^
