RichardK said:New growth curling and yellowing is magnesium deficiency. Get some epsom salts, disolve 1 tablespoon into a gallon of water and spray on tops and bottoms of leaves.
Or sprinkle a tablespoon around the soil and water, do not do this twice though, you should see results in two days or so, and some of the worst leaves may not recover, so dont take this as the salts not working, check new growth for signs of recovery.
If they dont recover in 4 days try some Nitrogen as well.

allen said:Thanks for the replies guys its greatly apreciated, but you have got me torn between the two, bone meal or Blood meal.would anyone be able to advise me which of the answers is correct or are they both rich in nitrogen ?
Thanks.
allen said:Bloodmeal it is then, thanks Richard, but if it was lack of Nitrogen that was causing the problem, should it not be affecting all the chile plants, as they are all in the same compost?
On one of the the plants, the new leaves sprouting at the top of the plant have grown, but are really small and even more wrinkled up than the other plant, but the larger leaves are still ok, and are the normal green colour. This is really confusing me so it is.
Calcium deficiency symptoms appear initially as generally stunted plant growth, necrotic leaf margins on young leaves or curling of the leaves, and eventual death of terminal buds and root tips. Generally the new growth of the plant is affected first. The mature leaves may be affected if the problem persists.[2]
