Is this common.....

Is it common for the bottom leaves to die and fall off? Mine are about 5 weeks old, a little over a week into flowering, and the lowest leaves died.

i know w/ gardening in general that if your lower leaves in potted plants keep dying it means youhr overwatering..
Whats you watering schedule?
I think it's normal for some leaves to die off during flowering especially closer to the end

Your ok, or shall I say they are ok. Especially if the rest looks ok.

I water about every other day to every 2 days....just whenever the soil feels dry. So it's not that big of a deal? Cool. Cultivate on then.
