You can remove fan leaves during flowering in much the same way you do during veg. Prune away large leaves that are overshadowing bud sites, as well as dead or dying fan leaves. One thing to keep in mind is that you should prune in intervals, giving at least a couple weeks between each session.
You should avoid pruning during flower. Pruning can be stressful for your plant, and pruning may slow bud development. You can remove large fan leaves if they are getting in the way of flowers, or if you feel they are using too much energy. But don't top or FIM your plants during flowering.
Plants have to spend energy growing leaves, stalks and buds. By trimming off the unnecessary leaves, more energy is left to put towards bud growth. Additionally, every time a bud site is pruned, two more will be created to take its place – leading to more buds on a single plant.
Usually, growers trim the fan leaves weeks before harvest, which is a period that leads to senescence, a phase in the plant cycle when the larger leaves start fading away. It is safe to start removing these dying leaves and continue until harvest.
All of the leaves of the cannabis plant are necessary for the process of photosynthesis to occur. Photosynthesis results in the production of sugars and other plant nutrients. Since the fan leaves are the largest leaves, they are essential to this process.
Whether you are removing fan leaves during the vegetative or flowering stages, it is important not to remove too many leaves at one time. Defoliating is a sensitive process, and if it is not done properly, the removal of the leaves can shock the plant, trigger early flowering, and produce a less impressive yield.
If you wait too long, your buds will be overripe and possibly ruined. If you harvest too early, the buds may not have finished growing (and developing their potency). Ultimately, the goal is to harvest when your plants' trichome and resin production is at its peak.
If there's any doubt about removing a particular leaf, play it safe and leave it in place. Don't remove more than 10–15% of a single plant's foliage. If you're more experienced, however, we recommend defoliating from the bottom of your plant up to 3–4 nodes from the top of the canopy.
Arguably the most common mistake that newbie cannabis cultivators make is stripping too many of the fan leaves from the plant. Cultivators should not prune more than 1/3 of the fan leaves on a cannabis plant in any given pruning session.
So there are three different times we recommend defoliating during Flower: Right before you switch to 12/12. Once between the beginning of Flower and the 3-week mark. 3 weeks after beginning flower is the last time you'll want to defoliate.

The areas on the plants with cannabis bud rot should be removed, then disposed of in a sealed bag away from the other plants. As soon as any symptoms appear on the plant, grey mold will follow rather quickly. The mold will spread throughout the plant, including all the buds, before infecting the other plants.
You'll want to lollipop your plants just before they begin flowering. We also recommend pruning—removing unnecessary branches—as well, although you should proceed slowly, and with a plan.
Lollipopping is a trimming technique that promotes healthy bud growth at the top of your cannabis plant.
Fan leaves support the cannabis plant throughout the vegetative phase. They enable plants to absorb enough energy from light that is then converted into food needed for growth. While they might not be a smokable component of the cannabis plant, it's a pity to dispose of them following the harvest.
Removing all the yellow leaves is not recommended surgery, especially for young plants. Correct identification of the source of the problem and swift remedial action can restore marijuana. Senescence is when plants will naturally yellow off and die. During the final weeks of flowering do not be alarmed.
Yes! During the night, late night to early morning you see new buds proliferating, at dawn or soon after they start to unfold. Daytime is the time for (most) plants to produce food by photosynthesis as that is when they get sunlight and the food/energy generated during the day is utilised at night in performing growth.
If you completely defoliate cannabis or remove too many leaves it severely compromises the plants ability to photosynthesise and grow effectively. For that reason, less experienced growers may wish to start slowly and gain experience gradually.
At the absolute minimum, you should wait until 50% of the trichomes are cloudy and 50% of the hairs have changed color. Again — do not harvest if fewer than 50% of the trichomes have turned milky. And do not harvest if fewer than 50% of the pistils have turned brown/orange.
Try some of the buds after 3 weeks
After about three weeks, your buds should be well cured and ready to smoke. That said, longer curing periods (up to six months) will further enhance flavour and potency with noticeable changes in quality. It's entirely up to you, but in the case of curing, patience is a virtue.
If you grow strains with an average flowering time, the majority of bud development will occur by the 6th week of bloom. In the last two weeks, the buds will mostly be ripening and not really growing much more in size. At this point, the previously white pistils on the buds will now slowly turn amber-brown.
If your cannabis plant does not get enough light, the lower leaves turn yellow and become flabby because they receive less light. The solution is similar: to correct the mode of light supply to the plant.
Bud rot develops in cannabis when botrytis cinerea, a type of fungus, infiltrates the plant. The fungus then develops inside the plant, before symptoms become visible. Early signs of bud rot eventually start showing on and around infected buds in the form of darkening and softening of the plant surface.
