It appears that the older leaves are yellowing which would be normal. Citrus do likes soil that drains but like quite a bit of fertilzer with plenty of Nitrogen and all the trace including Magnesium. I have read that a 5-1-3 NPK is ideal for citrus. A palm fertilizer would probabbly work well.

5-1-3 ratio isn't too far off palm special fert., which has everything in it.
Thanks Jubaea.

Anybody ever give citrus an Epsom Salts "tonic"? (making soil more acidic?)

I wish Laaz would chime in. He is a Citrus Guru.

I have not heard of giving Citrus any salts. A teaspoon of vinegar mixed with its water is recommended.

Al's gritty mix is a soil formula developed by a nice fella named...Al. You can find it on gardenweb.com

I use the 5:1:1 which is 5 parts pine bark chips, 1 part perlite, and 1 part peat. I also throw in some crushed granite. Kind of compromise between the two mixes.

Laaz probably has his hands full on his site...and fighting off storms.
He provided some good info several years ago when I had two Calamondin Orange trees.
But they`ve since both gone belly-up.

very helpful.
Now I get it.

Thanks!

Epsom Salts are a source of Magnesium and can be used correct or prevent a deficiency. Be carful as too much of a good thing can block the uptake of other nutrients. I believe too much Mg can block the uptake of Ca?
