First ever grow need defoliating advice please week 8 autoflower any advice or thoughts on how I'm doing so far also appreciated, many thanks!

Judging from the photos ... Yes. This is going to help with airflow and it helps flower sites that aren't getting enough light get adequate light. I do it all the time to my autoflowers works like a charm. Just don't do any after week 3 of flower it could cause unwanted stress. Hopefully, I answered your question and remember " Happy Growing and Free your mind one puff at a time ".

Hey! They're doing pretty good given the conditions you've mentioned, great job! Normally when defoliating it's just the big fan leaves but I recommend you don't do anything and just let her do her thing. Autos can get stressed quite easily and you wouldn't want that in flower that could cause her to stunt and not fully develop the buds. Good luck and happy growing!

You are about half way in flower. They will defoliate themselves at this point. No sense in stressing the plant right now

Wait until the last couple of weeks now before removing leaves. Cheers
