Cutting leaves is known as defoliating and its only needed when the plant is to big for the space and restricting airflow and light. It is not always needed and if you a newer growing I would not focus on it to much. If you need any other help reach out via DM "Direct Mailbox" its the little paper airplane logo/tab on the bottom right hand corner of your screen. Good Luck!

Only cut leaves when they cause problems. There are 2 problems that leaves can cause that could be a reason for cutting leaves. The first problem is when they stack on eachother and moist can not escape and transpare from the bottom of the leave. The second problem is that a large leave is blocking the light for a big part of the plant. Next to those reasons I would not cut leaves because you are just damaging the plant for nothing.

Looking at your current grow you wont need to do any defoliation. Your plant is very open and is getting the most light it can. If a leaf is covering a bud site its better to bend it down then to cut it off. You want all the energy you can get to make big buds. Happy Growing.
