Is this happening because of flowering?

[Bomeray]

So this plant just started its third week of flowering. I have been using flowering nutrients and stopped the veg nutes 3 weeks ago. I was just wondering if the leaves on the bottom of the plant will start doing this because of flowering or is there some deficiencies. They literally just fall off when touched.
Thanks!

Also i want to know what you all think about defoliating? Should i defoliate the plants that are flowering or just let them do their thing?

It's ok and don't defoliate.

Slightly deficient N. Don't add any though. Next time wait a bit longer before switching to bloom nutes.

Okay thanks! Yea i went straight from veg nutes on one feed to bloom nutes the next.

Plants look great. Yellow leaves at bottom of plant are normal. Don’t defoliate. Continue with bloom nutes. Remove any fallen leaves from soil to prevent mold and any hanging yellow leaves on plant to improve airflow which helps prevent powdery mildew and bud rot.
