Hi Buddy great looking plants. I have little experience. But as far as I know if your plants have responded great to Defoliation during the whole grow there should not be a problem Removing any Un necessary leaves, you need to make sure that your root system is healthy and up taking The necessary nutrition. To me buddy Defoliation is been always necessary when training a plant they all tend to get bushy after any training methods. Be slow on Defoliation take your time and remove leaves only covering bud sites and ones that don't get any light you will notice the once not receiving light are dropping when lights on, you don't want to over do to stun her right now in flower because off to little leaves and making her work to hard 😓. Good luck and help this helps.
