No, it's better to wait until you see signs of flowers, like a few pistils. You can also remove the large leaves at the top during the stretch that’s coming up; they grow the fastest and cover half of the rest, consuming energy during the stretch through growth and shading, probably more than they provide to the rest of the plant. And never cut too much from the bottom; your plant is still growing out and the structure allows multiple buds to get light. Really just the shoots on the lower 10 cm for now, or everything below your leaf layer there; I would leave everything at height and just below that and trim more freely. Many people over-trim their plants unnecessarily; you only want to remove leaves that cover other large parts and leaves and growth that hardly gets any light and is weak. The rest is functional, and removing it doesn't help at all. It's better not to trim at all before you take away all the energy from the plant.
