How do these 5 lovelies look?

Their autos and the leaves seem to fall off on their own. I try best not to cut a thing off my girls unless absolutely necessary. But I would gladly give it a try. I learned everything I learned about growing from growdiaries. I love the quick responses. Should I only take the biggest/oldest leaves. Or should I leave them alone cause their autos?

They look great, the only thing I would do (as others have mentioned) is a little bit of cleanup under the canopy in the interest of improving airflow.

Farei una defogliazione per migliorare illuminazione alle zone inferiore e circolazione dell'aria
