Hey there!
Allow me to make it simple for you: these are some of the first set of leaves she kept since she was a seedling. You could very well remove it at this later stage as part of a period defoliation.
I normally defoliate to maximise direct light exposure to the bud sites. I do so almost daily ion tiny, small, manageable rounds, making sure never to deprive the plant of needed fan leaves.
You are at week 6, I think a light defoliation (include this one for cosmetic reasons) won't hurt.
By the way, excellent strain you picked: It is in my next run for sure.
Do drop me a DM and I will be glad to contribute to your questions as best as I can.
