If you know you've overfertilized, you should be flushing hard now- at least 3X container volume ( ie, a 5 gallon pot needs 15 gallons of H20 minimum)

If you want a good yeild, yer gonna need better lighting. And a whole lot of other shit.

If a plant has pistilate and stamenate flowers, then it's a hermie. It will produce HEAVILY seeded bud. It will also cause ALL other plants in the room to produce HEAVILY seeded bud. Yer call- I'd lose it.
