The lemon tree's leaves in our garden has been yellowing starting out as spots/patches before turning the whole leaves yellow. We notice that a lot of the newer leaves growing out at the top of the tree has also started curling up, with some sort of sludge on them while others are just riddled with holes. What is wrong with our tree and what can we do to fix it hopefully? We have had quite a wet weather this past week so I don't think its from lack of water at least.
