7 this is my thinking on the defol... during veg... I don't really go by a time frame... King did tell me to do a major defol about a week to 10 days before going into flower but I have always been to short on space to let them go that long without feeling like they needed ventilation so I just pinch off the leaves if they are blocking a site or getting to thick....... IMO it does stall the girls for 5-7 days when I strip them naked but when I just pinch a few here and there... they don't seem to even notice.... I do more of a timed defol once the girls are in flower... at day 21-25 and day 45 or close to it and I still pinch a few here and there in between if they are in the way of the light penetrating to the bottom nugs.... Your girls are looking healthy so IMO you will be fine to pinch off any that are in the way of air flow or light penetration.....
