I think if you can keep a close eye on various parts of the plant and you see different trichrome color and maturity, same with pistils, then yes, harvesting in sections is ok. However youll want to be careful of your cut sections, you dont want any debris or germs getting in there. So if you harvest 1 plant in sections try and keep the harvests fairly close together, not weeks apart. And its definitely alright harvesting 1 plant before the others are ready, all plants are different and their times are different, even with same strains.
Good luck with the harvest, now the exhausting part of trimming comes. Ugh
