So i am going into week 5 here soon on my auto flower and its getting pretty bushy, i'm starting to see signs of sex with calyx producing pistils, can i defoliate to make sure she gets all the light she can or would that stunt her at this point??
Removing a few fan leaves to let light in won’t stunt growth all that much. It’s topping and some other high stress techniques that really delivers the pain to the plant.
I mean don’t go crazy and remove all the fan leaves but look at your plant and strategically remove the leaves that hide bud sites from getting nice light. I also remove the jankiest looking leaves first when I defoliate. That’s if you have janky looking leaves.
Hope that answers your question.
Cheers!
