Need to know if i should harvest

Ok so i have 3 very large bc big bud plants and they have out grown there box, the buds are making them hangdown, some buds are too close to the light and drying out. Im not too sure what i should do. Some buds like the upper ones are probably 60% orange and 40% white but my low4er buds are white with orange just coming in. My lighting must not be adequately hitting all the lights but theres not much i can do from this point. Is it possible to harvest half of every plant or something crazy like that?

Any help would be appreciated. I believe it has been 50-55 days flowering on a plant that has a flower time of 55-60.

If your doing the macroscopic determination of ripeness then based on your percentages you can harvest. And sure if you want to wait for the bottoms to catch up in ripeness with the tops. I just dont since I just want to move on to the next flowering cycle for other strains.

you can harvest the top half, put your plant on an upside down empty bucket, wait a week if need be. IF, like calicat, you have a system and its just better to get it done and put the next one in the budding room, those clear tri's on the smaller lower buds are not going to hurt much. I have found that i actually never over mature while at the same time, my lower buds are fairly done also. I also usually have another one waiting. personal perpetual grow.

You can harvest the buds that are ready with no problem, I've done it many times.

Yes, you can take the tops of the plants and leave the lower parts to finish.

Thanks for the quick responses everyone, im going to go ahead and take the top halfs of em and let the bottom go for another week.
