Anytime you have a plant growing, that's a great opportunity to learn. Unless your wife absolutely can't wait 2-3 weeks, now's a great time to get experience with ripening. Even if this grow's not a everything you wanted, it's still great experience which you
will appreciate when you reach this point in your next grow. (You'll feel like you've been down this road before.).
Now would be a great time to experiment (lightly) with
epsom salt & AK kelp, mentioned a week ago. (<<link) Or, if you want to try a "bloom booster," get something high in P&K. (But, I think that's more risky. Alternating between a 1/4-1/2tsp/gal epsom salt, and 1-2 Tbsp Pennington shouldn't be a problem.). That's the sort of stuff that would be really handy to have played with with when you reach this point in your next grow; with more on the line you'll be more nervous about things like this, etc. You've got a perfect opportunity with a plant that you're not "hoping for more" with.
Regarding harvesting when clear: I've always noticed they can be clear for a long time. They were probably clear two weeks ago. They may be clear in another two weeks. If you wait for a little cloudy, you'll at least have a reference point for when in the "clear lifespan." Seems like there should at least be some brown pistils.
The whole "expected flower time" in this case doesn't seem fruitful (no pun intended.). Those estimates are based upon the plant being driven by sufficient light. Your plant wasn't for 4 weeks. It languished in a sleepy, flowery state. Since it wasn't really driven to finish, I don't think those 4 weeks count for much in terms of "lifespan." It was just on hiatus. It might have remained in that state for months, eventually herming. When you added more light, it could have had 4-6 weeks left. (I.e, the first 4 weeks might have only counted as 1-2 weeks.). If you let it continue, you'll learn something about that which might be helpful to someone else in the future (when you see someone in this same situation).
