classic "N" nitrogen toxicity (to much) presents it's self as dark green colored leaves and also the leaves look like a "claw", this is a common issue, Just flush for one week:" Remember once you see a problem you are all ready two weeks behind in fixing it" - if in flower stage the plant does not need much "N" at all Hope this helps!!!!
Stop "N" use and increase "P" & "K" ( "P" being in greater amounts of "K" and "N" should be lower than "P") plant need "P" for flower development and "N" for vegation growth

check your pH. I would start there. if it's out of range fix it, if it's in range then you might be looking at...
You have some leaves in the middle that look like a pH problem.
Bottom growth looks way to green.
Leaves are clawing, like was said (N) toxic.
Leaf edges are curling up, I can see on a couple a leaves. That could be a magnesium def.

Not true. Plants actually need low-moderate amounts of P during flowering, but still need consistent amounts of "N" to retain healthy foliage and thus healthy plants. Also, their TRUE requirements for K are actually higher than their requirements for "P" during flowering. I would never recommend stopping the use of N, but curtailing N for awhile until the plant shows a need for more nitrogen is probably the best bet. In addition, different plants have different requirements. Some are N hogs during flower, while some aren't. It's all about "reading" the plants.

You are fight a little 'n' will not hurt, just perfere to use no "n" and good amounts for P &K. Thnaks for you input, I learned something new, you know - comes down to personal choice. PEACE
