most of my buds look like that so i just have 1 picture. i harvested my cola 3 days ago. and now harvesting the smaller buds. 8 weeks and like 5 days
The best way to tell is to let the trichomes speak for themselves! get a pocket microscope, and check them out! if the trichs are clear, they are not ready! the THC has not built up its full potency. If they are milky, expect a good head buzz, a very cerebral and social high. If you have amber (brown) trichs, one can expect a couch lock style high. Most growers generally harvest when the trichs are 50% amber 50% milky, but it is all up to your preference! My guess, looking at the picture is that your plant has at least a few days to continue flowering. If you look at the pistils (little hairs on the bud) you want them to be just about all brown/red/orange, and I still see a hand full of white pistils at the top of the Cola. Don't rush it man! Let it reach its full potency. Nice buds by the way!
If i was you, I personally would let it flower for only a few more days, only feeding her water. (no more nutes) But again, you are the grower, you are the boss. Make the plant how you want it!
oh and i have another problem, bud doesnt smell!!! im drying cola and i waas sniffing it, and it doesnt smell at all! i guess it smells like pine needles? thats what i read some other people saying when it doesnt really smell. but when itouch it and smell my fignrs, it smells . whaht can be wrong? the nutes? i read that it may be the humidity. too low?
