Unzie. The most important peice of advice i could give you is to NOT RUSH. We can't make it rain any more then we can make a plant finish faster.
With that being said. Lets just eyeball your plant....first and for most the best way to tell when a plant is 100% ready is by checking the trichomes (the white crystals on the top of your buds) you can do this with a powerful magnifygalss such as a 420 scope or a jewlers scope. You can also turn your digital camera to macro (or whatever best quality shot you can take) and take the closest stillest shot possible then load on your computer and zoom in or zoom with camera after you take the shot to look at the trichomes. You can also order a usb microscope.
What your looking for is the 3 stages that trichomes change to.
1)clear - trichromes are at there first stages of productiion. THC is low to none.
2)cloudy - trichomes appear to be milky or foggy in color - once all trichomes appear %100 cloudy, this is at the point where THC is at its max - Psychoactive cannabis are more profound then the CBDs will be.
3)amber - Tichomes will look redish or brownish in color - This is the point when THC starts to decrees and CBD and CBN (CBD is the "medicince" part and CBN is what happens to THC when it gets older and CBN creates the narcotoic not CBD) is more profound which is why med patients like 50/50 (cloudy/amber)
How do you tell the %?
a few facts I know are true.
1)dif parts of your plants finish at dif times
2)dif part of your plant are more/less potent then other parts of your plant.
That being said you can't go around killing your self trying to look at every inch of the plant with a half inch piece of glass right? SO what you do is pretty simple. Grab your scope or whatever thing you need to check the trichomes and you test the BOTTOM, MIDDLE, TOP in one spot on the buds normally the top (some do the bottom. i forget which part of the bud develops first) and within the view of the 1/2 inch, you look at all the trichomes and from there you get your % if there is a few hundred and they all look like glass then there all clear. If they look cloudy then there almost there. so on and so forth.
Lastlly if you don't have a scope you can just look at the leafs and the pistles (white hairs coming off the buds). Just like in nature. when the season goes from summer to fall. the leafs on the trees change colore marking the end of the life cycle for that season. Cannabis reacts the same way. During the last weeks of its life the leafs will go from green and then fade to mainllly yelow but depending on genetics the leafs can change many colors. You will also notice the hairs on your buds going from white to either red/brown/purple/pink or something other then white. IF doing the eyeball method. alot of people will wait for 75% of the hairs to change color. The hairs changing color also marks the end of the life cycle for your plant
Now that my stoner rant is over I would say a month since there is 0 yellowing and 0 change in pistle color. Also the buds looks like they haven't started swelling up yet.
A little bet of advice to help slow down the erg would be to plant a couple more seeds in the ground that way you have something else to start on. Then when it does come time for your ladies to get chopped you have a new rotation to finish up. then by the time your done smoking up your sweet buds you'll have more done !
hope the info helped.
