with Daisy. Go for some fertilizer that is specifically formulated for citrus if you can get it.
Also, I'd give it another try to clean the leaves. That chalky deposit on them is blocking their ability to absorb sunlight, and you're only giving it half a day's sun as it is.
I use a tsp. of mayonnaise whisked with a couple of tablespoons of warm water on my orchid leaves if they get hard water deposits on them. Put this concoction on a paper towel and rub it on the leaves then wipe them with another dry paper towel. The acid from the mayo will dissolve the deposits and the oil will shine up the leaves again. Don't use straight mayo! It will be too acidic and leave too much oil.
