Some of the lower fan leaves looked very dark, almost like a bluish-green. Is that what they look like or was that the result of the lighting used when the pictures were taken?

"The Claw" is the result of nitrogen toxicity. It destroys the plant's vascular system slowing down moisture and nutrient uptake to the effected leaves/areas, normally the upper/new/newer fan leaves. At the same time it increases plant transpiration so the leaves that are not getting as much moisture and nutrition as they need are losing moisture (transpiration) at an increased rate.

The reason I asked about the actual color of the lower fan leaves is if they are a very dark green, or worse, a bluish-green that is a sign of excess nitrogen and one more clue that what is happening farther up the plant is actually "The Claw" and not some other malady.

Damaged vascular systems do not heal, they do not repair themselves, the damage remains. If caught very early flushing can somewhat minimize the damage but once a vascular system breaks down even if you flush every bit of nitrogen, and everything else, from your soil the plants will remain incapable of taking in as much moisture as they need and they will not come back from it and they will likely only get worse as time passes.

Its the lights I use flour to help wit low lit areas

Its the lites
