you can over feed and this draws water out of the cells. so dont add any more feed.

I hope you don't mind me joining in your question Kath.
Would this be for all plants SBG. I've a camellia in a simlar state and have been feeding thinking it was lacking iron.

yes over feeding will cause similar problems. for camellias etc it has to be sequesrinated [spelling?] iron. something to do with the chemical form of iron used. yellowing leaves could be due to lack of magnesium as that element is needed for the manufacture of chlorophyll, the green pigment. try a dose of epsom salts and see if that greens it up.

Thanks SBG I shall do that as it was look good .

Do you think it will recover?

should do. :o)
