Both work just fine, if you take clones right before flowering and then veg those clones and clone them again before flowering that’s just like “refresh†a mother, often, when a mom gets too big and too rooted you have to take a new clone anyway so if you plan it right it work perfectly. I don’t keep the same mom for more than a few months because if you want the plant to stay healthy and vigorous it has to be growing. So to keep her under control I’ve been cloning every month and leaving one clone to take clones next time, I don’t even flower the moms cause I take all the branches away.
