You can take off more than you would think and she will be fine, but start with the lower stuff, and the. Just look and see if bud sites can be opened up by defoliating that area, if so, go for it. The plant will be just fine. Now is the time to do it during the stretch, plus that will stunt her just a touch and slow her upward growth down as well.
If you are nervous,...start and post a photo with me tagged,..,I will check and let you know. All good man. She's going to be sweet!
