I have another question about pruning.... is it necessery? And if it is, how do i do that? I watched many videos, but im dumb, and it is still not clear which leaf i should cut! Do i need to cut the big older leafs or the younger small leafs? What happens if im not cutting any leafs?
So this is only my opinion... as a first time grower keep it simple so... your reasons to prune.
1 Airflow... if your plants are to dense and you can't get proper Airflow.
2. Damahed, infected or unhealthy leaves. As leaves age the become less efficient at photosynthesis and the plant may cannibalize them for nutrients. These leaves are usually the first to show sign of infection. Any leaves resting on the soil or container or stacking on other leaves cause them to sweat.
3. Shading new growth. If you have huge old fan leaves blocking newer growth sites. You want your canopy to absorb as much light as possible so when removing larger leaves from the upper canopy make sure there are leaves below to catch the light. You don't want spaces that allow the light to go through the plant and not be absorbed.
When pruning you want to remove the largest oldest leaves. They are less efficient at photosynthesis and cover a large space that could be going to more efficient leaves.
Typically after 60 days or so the plant will naturally start shedding these on its own.
Before flipping to flower often growers will do what's called a lollipop where the remove most of the foliage about 1/3 of the plant from the bottom up. This increases airflow and removes tiny growth and leaves that will not get much light.
