Pictures, pictures, pictures...
We can hypothesize all day long and give you vague guesses....
When you induce flowering, this is always followed by a stretch. Normally about 2 times original size before flower. Nothing new there.
Did someone read their grow journels and watch their grow videos?
Someone may have some homework ahead of them...
Drooping leaves... but they look healthy...
How long since you watered.... or perhaps over-watered?
Again, pictures would help, but research will help you much more.
Good luck buddy
