The endo have a history in organics both parents were adjusted to that and the GDP was in high brix coco,so that might be a factor ,that and hybrid vigor,mine is a little beast I'm expecting a 2 foot budcicle, I put in flower not much bigger than yours are now
I use an ionizing air purifier to help with free floating pollen so far it's been a big help I put it near the exhaust of the tent with a pollen source or in the tent with plants I'm treating with CS,it grounds out floating particles to the nearest metal ground ,my filter is that oreck xl thing with the Truman cell tech it does a great job of making the room smell like nothing,even over powers the airfreshner and ONA gel !
