Harvest time?

We are coming to the end of our first grow from seeds and have done everything by the book "Marijuana Buds For Less". Both plants look good with nice looking buds on them. They still have quite a few white hairs and we need to know when to harvest and do we have to harvest all at once or can we harvest a little at a time as they mature?

here you go just take a look at this ..https://www.rollitup.org/harvesting-curing/28072-harvest-time-tutorial.html

If you truly get mature buds while some of the others are not yet ripe, then go ahead and harvest what is rad and let the rest ripen on the plant.

I've heard that on top of the white hairs, to look at the trichomes. get yourself a han-held magnifier 30x or better with a built in light. when you have a 50/50 ratio of white/white-amber colored trichomes this is an indicater that the buds are ready for harvest. I hope this is helpful!
