hey there Dr Jones, unfortunately pruning the leafs off at this stage wont help it grow, it has all the leafs it needs to make flowers as it is. Remember that right now the plant is already making leafs as well as the tent gets much brighter when you close it than when it's open , there's hardly any shade there because the plant already has the correct shape (shape of a bush) . So roll with the punches and ride to the harvest. Hope this helps ! 🚀
