Seeds take to form--how long?

I must have had a plant switch, because I've noticed some seeds...ugh

I was just curious--how long do seeds take to grow and form, from the time the plant is pollenated to the time the seeds are ready?

(And what can trigger it--too humid or too dry? Too many nutes? That could have been the only stressors...can it just flip on it's own?)

4-6 weeks.
Or tell they turn brown.

MJ is a dual sex plant.
Often it's nothing we did, just a roll of the genetic dice.


Ps I've grown several hermi seeds that did herm on me.
Free fems for the outdoor grow...

Ok, thanks...I was thinking maybe I let em flower too long, but if it takes 4-6 weeks, then it wa definitely something else...

Do you know if Miracle Grow can trigger it? I shouldn't admit publicly I was cheating a little this last round, but I'm wondering now if that messed with them a little...maybe the wrong nutes/too many nutes, etc.

Thankfully, it wasn't all of them (I've only found 11 so far), but I was just surprised to see any seeds at all--
