Tomato leaves challenged

Client called and has been having poor tomato production.  Leaves are narrow and unthrifty, tomato production low.  I suspect low nutrition and irregular watering.  Suggested having the soil tested.  Client has fertilized regularly with composted horse manure and uses old hay mulch.  Any other thoughts would be appreciated.  What am I missing?

  1. George: The symptoms in the second photo might be viral in nature. Also, where did the grower get his/her mulch? I have seen situations where there was a growth regulator herbicide used during production of a grain crop and enough residues remained in the straw that it caused problems in tomatoes. Just some thoughts. Brian (:))
