   Well here is my uneducated guess...
The movement of water across the root cell membrane is regulated by the
concentration of dissolved fertilizer salts in soil solution relative to the
dissolved salts within the cell. As fertilizer salts dissolve in water, they
raise the osmotic pressure of the solution. water always moves from the side
of the membrane with lower osmotic pressure to the side with higher osmotic
pressure.
   Root cells actively absorb fertilizer salts from soil solution and, under
normal conditions maintain a higher osmotic pressure. Thus, water is absorbed
into the root cells.
   HOWEVER, if excess fertilizer salts are applied and raise the osmotic
pressure of soil solution, water cannot enter the cell and may actively move
out of it. What results is fertilizer burn or PHYSIOLOGICAL DROUGHT !!!  
   The only thing I can say is that for your current soil make up the amount
of fertilizer you are adding just might be pushing the plant to it breaking
point. In my opinion cut down the fertilizer for now and pump up the water
for a couple of days. That should do the trick.
   Well, that was just MY TWO CENTS don't take it as gospel....
Take care all
