The veining is a bit curious, I had this once; it might indicate a deficiency of magnesium. Many plant symptoms can be very similar, yet caused by different issues (deficiency of one nutrient or too much of another).

I would stop the API Leaf Zone, this is only iron and potassium, and these will be in the root tabs. Too much iron can cause trouble; I think in one of the photos there is a sword plant in the back that has brown spots on the leaf, that is iron excess. [I am battling this myself, as it can also be caused by a c alcium deficiency which is my particular issue with my soft water.] Contrary to what one reads elsewhere, swords do not need heavy iron. But more to the point other nutrients may be missing or insufficient. Flourish Comp would be a better choice because it has all nutrients and in proportion. Another near-identical product is Brightwell Aquatics plant supplement, can't remember the exact name.

That's on one of the old original leaves, I haven't seen that on any of the new leaves.

Should I cut off all the original leaves?

On another note, I've been having a reading of 0.5 on the ammonia (lowest showing on API Liquid Test). On Sunday I saw a small reading of 0.25 on Nitrite (again smallest reading). Today it's zero across the board including Nitrates. I can only assume the plants are hungrily eating all the Nitrogen, but I would have expected the Ammonia to stay as on Saturday I added 3 more Serpae Tetras to get their school up to proper numbers, plus an Anubias Nana. I wouldn't think the Anubias as a slow grower would be sucking up much, a couple of the Wisteria though are doing great, a couple not so much but still showing slow growth.

When the original leaves begin to yellow, they can be cut off. But until then, leave them. Some nutrients are mobile, and plants can move these from old leaves to use for new leaf production, so removing the leaf would remove these nutrients from the plant. Nitrogen, phosphorus, potassium, magnesium and zinc are mobile nutrients. [Immobile nutrients like calcium, copper, iron, manganese, boron and sulphur cannot be moved, hence the term.]

With sufficient fast-growing plants--and Wisteria is certainly that--you will not see any rise in ammonia or nitrite when adding fish. It is astounding how much ammonia a plant can either assimilate (as nutrient) or take up (as toxic ammonia). This is why I can set up a new 115g tank with 95 fish on the first day and never have an issue. Plants are nature's filters, and they are so good at it.

Well, I took some tap water over to the local petsmart and had them test it, they'll do that for free so what the heck.

Hardness: 25 ppm
Alkalinity: ~40 ppm (this one was between colors so could be half way up to the next, or half way down)

My pH I have a terrible time of figuring out. I can't tell the difference on the API card between 6.8, 7.0, and 7.2 .... but it is one of those. Lamp lights, sunlight, indirect sunlight, they all look the same =/ (even my wife thinks so, either we're both going color blind or they're really close in shades =p)

So with such soft water, that would mean calcium and magnesium are probably too low right?

Before messing with calcium/magnesium supplementation, I would try the easy fix and use a complete liquid fertilizer like Flourish Comporhensive or the Brightwell product. There is some calcium andmagnesium in both of these along with everything else.
