Yellowing

I'm about 4weeks into the flowering cycle and my some of her leaves are starting to turn yellow. The leaves are turning yellow from the out side inward toward the center of the leaf. any advise?

does it start at the bottom of the plant and mocve its way up

your plant is growing and has N-deficiency which needs some extra Nitrogen when stretching during flowering. after it stops growing slow down on the Nitrogen and go back to normal nutes..

My lady is about 4 weeks into the flowering stage and some of her leaves are starting to turn yellow. the yellowing is starting from the edges and working toward the center. Any advice and what could be causing my problem? Using Dyna Gro bloom ppm are at 560. I just added something new about a week a go. my lady wasn't under no stress when i added the gravity. is this stress or just normal for this time during the cycle?:

I'm haveing the same problem but I'm now at week 9 into veg. What I've been reading is it could be bcuz not enough n or k so I started useing 24 8 16 n it has seemed to slow or stop the yellowing but my sick leaves continue to die but doesn't realy effect the new grouth. And some people say its bcuz of nute lock out but I don't think its that just bcuz I just started useing the like 2 weeks ago so I would flush it. Hope this gives u an idea
