Need to know if these are close to being done

there is pictures of one of my plants where the hairs are starting to change colors...the rest of the pics is other plants and my room
If some of the buds are ready...can you trim off just those branches to start drying out or will that be too much damage for the plant to handle. thanks for your feedback

Wait until you don't see all those white hairs. You can harvest in sections - usually start with the colas and cut the lower buds a week or two later.

Looks like you need better flowering food, and more light to ease the stretching and increase yield.

ya this was just my first grow...they were moved from one idea to another and stretched in the process. I've got plans for the next round that includes both better food and more lighting. I'm satisfied with this since it is my first but not happy with it overall. I know i won't be pulling much off of these but at least it's something! Next grow I hope will be MUCH better!
