Meyer Lemon in distress. What is wrong with this tree?

 

A very healthy Meyer Lemon the first summer. 2012.

 

 

A nice healthy crop of lemons. The leaves seem to be starting to pale. This was over the winter of 2012/2013.

I think I have figured out why my Meyer Lemon is very pale and sickly this last year. I have poured on the Seaweed and that helped quite a bit. I've just returned home from Hawaii and the lemon and even the lime are in distress. I inspected and found tiny spider webs, so off to Dr Google I went. I sprinkled a soap solution on them to kill the now identified spider mites. In my reading I've come to the conclusion that it is a classic chicken and egg situation. I now believe that the plant is magnesium deficient and the mites have come in to feast on a weakened plant. Tomorrow I will give them a good dose of Dolomite Lime which contains magnesium. I also gave them some bone meal. I had already given them a good dose of seaweed.

 

I will update on the progress of this poor abused little tree!
