Diseases or poisoning?
Pepper, bell Iran
Hello,
Do you know what the problem with these peppers?
Leaves necrosis started from old leaves and spread to new leaves.
Root and crown are good and they are not showing any symptoms. Is it possible that leaves have a deficiency of microelement, for example, Magnesium deficiency ? or its because of poisoning from chicken manure?
Thank you so much.

I agree it may be due to magnesium deficiency. It is very common in pepper plants when the there is an extremely hot, dry weather or excess application of potassium or calcium. Normally, symptoms first appear on older leaves. The main symptoms are "Bright yellowing of older leaves that spread from the tips and margins towards the main veins, often leaving a green triangular area near the base of the leaf."

By looking at the images it appears that yellowing of the leaves has in the interveinal areas and veins remained green.
