Take them off for light penetration?
you do understand the purpose of leaves right?
Trimming leaves during veg allows more light to the lower nodes. Thusly they grow much faster and you get more buds. Shouldn't be "neccesary " for a plant that's growing naturally but if you're doing that then your wasting your light anyway.
That was only vegged for 7 weeks and I was taking a shopping bag full of leaves off per week.
Can even get autos that size using the same treatment.
Yes they need the leaves to absorb light but for every one you cut off, you expose a bunch more so they grow back exponentially with a lot more bud sites if you do it right.
