oh bro, i feel for ya, nothing worse than a late flower hermi...but 7 weeks isnt bad if the pollen sacks r just poppin up...look at it this way, it will take atleast a week for the pollen to develop, and atleast another 3-4 days after the pollen drops b4 the seed even starts to really form...i say finish her, and pluck whatever balls you see..
EDIT: but if you got clones, kill the little fuckers, n start over with a new seed, also, alot of times the hermi isnt from any stress, its more likly to be in the genetics from the start...
