Patience...they don't look like ripe at all--it def. looks like a few more weeks.
If you won't be looking at trichs to determine ripeness, then wait until almost all of those hairs are red and really receding...
from the pic--they are still standing pretty tall and don't look all that red/orange yet...and wait for those calyxes to swell--that's where your weight and buzz is anyway...
Do you know the strain?
I personally can't stand to see people cut their bud too early...what a true waste of herb and time.
Good Luck--if all goes well--in a few weeks your smoke will be sticky, sweet and ripe
