Default yellowing leaves on chili pepper plant

Just be careful not to think too much into it. It's very easy to get bogged
down in the details of mineral deficienies and plant diseases and drive
yourself crazy trying to treat all these percieved problems. I would highly
recommend having an extensive soil test done if you are pretty sure your
problem is a mineral deficiencies. Your local agricultural extension will
probubly do these tests for free, just request a full trace mineral work-up.
It's important to be sure becuase having too much of some minerals can be as
bad or worse than not having enough, and you could accidentally overdose
your plant. Just be careful.

One thing no one has mentioned yet is SALT. It generally requires quite a
bit in order to hurt your plants but it is possible. If you are using
softened water to water your plants it can build up in the soil and cause
symptoms similiar to what you are describing. If you happen to live fairly
close to the ocean, particularly on the West Coast where the air currents
bring rain from off the ocean, it could also have built up in your soil. If
nothing else its something to consider.

As to the minerals, Ironite is good for the iron issue, and for magnesium
you can try Epsom Salts, applied as a spray mixed with water. About 2
tablespoons per quart I believe is considered a good mixture. I am not sure
what provides magnease.

Thanks a lot for the excerpts -- based on
your citations it appears to me that my plant
could be lacking all of Fe, Mg, and Mn,
but at the very least 2 of the above -- Fe
and Mg for sure, and probably Mn, too.

I might actually have some KMnO4 and
FeCl3, but I'm not sure if they make a
good fertilizer.... ;-)

This is an except from a website dealing with plant nutrition...

Magnesium is a critical structural component of the chlorophyll molecule

and
is necessary for functioning of plant enzymes to produce carbohydrates,
sugars and fats. It is used for fruit and nut formation and essential

for
germination of seeds. Deficient plants appear chlorotic, show yellowing
between veins of older leaves; leaves may droop. Magnesium is leached by
watering and must be supplied when feeding. It can be applied as a

foliar
spray to correct deficiencies.

I hope you can find this information helpful...

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.
