help with leaf deformation

I have 36 plants on the side of my house the top leaves are scrawny and curling, the rest of the plant pale yellow green with very few flowers. All of my potted plants are doing well. here are some pictures
 

 
 
I have a similar problem in my aquaponics setup. I'm almost sure it has something to do with the water...
 
Anyone know what deficiencies this can be caused from?

The guide pic I have says that would be calcium deficiancy.
 
New leaves misshapen or stunted.  Existing leaves remain green.

Another guide said it also could be signs of a K or Mg overdose.

This one may help with the hydro issue:
