Oh yeah on the other 2 nutrients it says...

Iron is necessary for many enzyme functions and as a catalyst for the synthesis of chlorophyll. It is essential for the young growing parts of plants. Deficiencies are pale leaf color of young leaves followed by yellowing of leaves and large veins. Iron is lost by leaching and is held in the lower portions of the soil structure. Under conditions of high pH (alkaline) iron is rendered unavailable to plants. When soils are alkaline, iron may be abundant but unavailable. Applications of an acid nutrient formula containing iron chelates, held in soluble form, should correct the problem.

Manganese is involved in enzyme activity for photosynthesis, respiration, and nitrogen metabolism. Deficiency in young leaves may show a network of green veins on a light green background similar to an iron deficiency. In the advanced stages the light green parts become white, and leaves are shed. Brownish, black, or grayish spots may appear next to the veins. In neutral or alkaline soils plants often show deficiency symptoms. In highly acid soils, manganese may be available to the extent that it results in toxicity.

If your plants are turning a mottled brown and yellow with splotches,
it is probably a blight. Peppers are relatives of the tomato and are
susceptible to the same diseases. If, however, the bottom leaves are
just turning yellow, it is probably simple choriosis (yellowing)
caused by excessive watering.


It's pretty much all the leaves that are turning yellow,
a few with brown splotches....

Overwatering could be an issue as I watered it a little
more than usual during a recent heatwave, which were
promptly followed by a few downpours.

I did some google search, and came up with magnesium,
manganese, and iron as possible minerals pepper plants
could be lacking, but I'm not sure about the symptoms
the lack of these might cause.
