Hi outnin and thanks for the response :)
the leaf is old, one of the first 4 bottom leaves. my duct fan is bigger than my tent size, exchanging more air pr min than there is inside, making a vaccum, drags in air like a champ. I frikking hope it's not poor ventilation. feels like that could make big problems down the road. Also have two fans (buying a new oscillating fan tomorrow) one on top blowing down and one at the bottom blowing straight. I would love to veg her longer, like you say - getting more out of it. If I per se super cropped them both tonight, would 3 weeks more for veg be enough and the containers, would they be sufficient? they are 4.2 gallons. I have a feeling that super cropping while make them fill out my space without losing height :)
