IHG - Velvet Breath & IHG Freebie

I'm questioning how close these plants are to harvest... Based on the breeders recommendation, we would be looking at about 2 more weeks. I am including photos of everything I possibly can, labeled. Freebie from inhouse: I have no idea what it is but its got crazy frost, trichs on the upper buds are starting to turn amber on it, lower buds show no amber but they do look milky (I think?). Velvet#1: More yellow than purple like the other two, stacked buds like crazy compared to the other two though. Super frosty. More of a gassy smell to it. Velvet#2: Definitely fading out nicely, turning a nice hint of purple on all of the tips Velvet#3: This one has been a little weird to me. It stopped putting on any new weight / buds earlier than the others and really hasn't generated any new pistols or anything in a few weeks. But also seemed to go purple really early on. I don't know if its just got a shorter lifecycle? Trichs on this one seem more amber than the others. I measured runoff to make sure it wasn't some kind of PH problem, runoff was 6.3, watering with 6.2 water. All in all... I am very happy with the plants so far. I am considering harvesting Velvet #3 but haven't seen any fade on the lower portions of the plant. I've seen some folks have said to harvest just the top buds and let the bottom finish up. I'd prefer not to go that route, I want a nice long dry and to pull these branches off all at once if possible. Would love anyone's feedback on what they can see from the pictures. I am not by any means impatient! I am more than happy to let these go a little longer if that is what they need. I think most of them can go just a little longer but this is the phase of growing I struggle with.
