Yellow leaves normal during flowering?

I have two plants outside, they were rootbound about 2-3 weeks ago, so I planted them in the ground. No more yellow leaves for about 2-3 weeks. Then today I came home from my girlfriends and all of the the little yellow leaves on the bottom are yellow. Is this normal for flowering? (about 5 weeks in). Thanks!

yeah perfectly normal..if they are a long flowering strain you might want to give a bit of nitrogen to help it out..if its a 6-8 week strain dont do a thing....

thats what i thought. yeah its nirvana white widow. i cannot wait til harvest. I am so pumped. waiting for them to fatten up.
