towards end of flowering stage question

My plants are towards of the end of flowering, it seems the buds are much further along in the middle of the plant, most of the hairs are orange some clouding of the trichomes, the upper big big buds still are mostly white hairs and clear trichomes. Once the middle buds are done should i be harvesting them and let the upper buds go longer or just harvest it all at once? Is this normal to happen?

thanks all

Personally, I let my primary tops tell me when to harvest. The little stuff in the middle is just along for the ride. It's all personal preference though, so give it a go and see if you're happy with the results. Next time, harvest it all at once and see if you like that.

Congrats on the harvest!
