Yikes. How much longer to harvest?
You have a couple choices.
Pick the male flowers individually- requires constant attention, a couple times per day just to get the bulk of them. You still can miss some.
Harvest the affected buds early. Be sure to seal off the main stem when you do this wiht a binder or laundry clip after making the cut.
Harvest the whole plant early.
Or just deal with the seeds.
None of these are ideal. What is the origin of those seeds again?
