Nice job! I happen to love LST clips - they make the process SO easy!
No, you don't have to do any defoliation at this point and I would strongly advise against it... I've just today read a fascinating article on defoliation which has changed my approach to the issue henceforth! There's a lot of blahblahblah at the beginning but if you stick with it, you'll get to the meat of the article and it will help you plan WHEN to defoliate and WHY .... here it is: https://www.growweedeasy.com/nebulas-super-simple-3-step-defoliation-tutorial
Always learning... always learning!
Good luck!
