Cannabis cultivators should avoid pruning cannabis plants leading up to the flower stage and definitely during the flowering stage. The best time to prune cannabis plants is early in the cultivation process, preferably in the first week or two of the vegetative growth stage.
Also to know is, should I cut off big fan leaves?
Removing these fan leaves opens up light and produces better air exchange to the lower canopy. Healthy leaves at the bottom of the canopy should be kept to trap valuable light from being lost and wasted. The more quality light a flowering site receives, the larger it will grow and the faster it will mature.
In this manner, when should you top the second time?
It is best to top your weed plants after they have grown 3 to 5 nodes. Once they have reached this size, they are strong enough to recover from the shock of being cut. If you want to top the new growth again, you should wait at least a week, perhaps 2, to give you plant time to recover from the previous topping.
Is it OK to trim leaves during flowering?
During flowering time, it is still possible to trim off lower branches, but you must be conservative and not cut off too much. Trimming any plant does cause some amount of stress, and overdoing it can send a plant into shock, sending all its resources to heal the areas you have cut off.
- Cut back to a bud that faces out, away from the central stem or trunk. …
- Leave about ½ inch between the bud and where you make your cut.
- Cut at an angle that slants down and away from the bud in order to discourage water from collecting on the wound and running towards the bud.
How And When To Remove Fan Leaves
- Leaves at the bottom of the plant that receives little light can be pruned.
- Fan leaves that create shadows over budding sites should be pruned to increase light penetration throughout the canopy, rather than just the tops.
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.
Sugar leaves and fan leaves both make excellent food and drink additives, even if you aren’t adept at making edibles. For instance: You can place the leaves in your tea for added flavor and a touch of psychoactive potency. You can grind them down and mix them into your salads, oatmeal, or just about anything else.
Even woody plants may be cut down to the ground and grow again. A redwood tree destroyed by fire survives by producing a circle of seedlings that sprout up around its scorched stump. Poplars are indefatigable, too. … It is recommended not to prune back any plant by more than two-thirds.
Here’s how to pinch (or tip) properly: Once your young plant has formed a few pairs of leaves on a stem, it is ready to be pinched. Plants grow buds at the base of each leaf, just above the point where the leaf connects to the stem.
Topping must be done when the plant has 3–4 nodes, but since autoflowers begin flowering by the third or fourth week, the plant should display 4 nodes by the beginning of week 3. Try not to cut too much since stress can severely reduce the yields. Do not Top or FIM if the plant has been overwatered or under-watered.
