yes, i defoliate my autos regularly to ensure light getting in to the lower branches, and also for keeping air circulation good to keep humidity in check
I defoliate at every feeding. I recently lollipopped my girls lol they havent skipped a beat. Most autos love it and yields and overall bud size and quality are improved.
Yes you can defoliate an auto but don’t go doing it all at once,I pick a few leafs when they are covering new growth and then I wait a couple days before I pick some more..i
