Don't just don't…
Just trust, leave it as it is, you don't have enough leaves to need to defoliate anyway…
You're taking the plant's lungs, the leaves that it uses for photosynthesis, gas exchange, and light absorption…
The fewer leaves, the slower the growth and the less flower formation…
It only makes sense if it's very densely grown, but in your case, you have more than enough space on all sides; if there's just one fan circulating the air, that's absolutely sufficient…
I made the same mistakes at the beginning, check out my grow to get a bit of understanding that even in dense growth, defoliation isn't even necessary…
You actually don't need to defoliate automatics since they stay relatively small and compact anyway.
