curly leaves and slowed growth please help!

[canoli]

Hello All this is my first post here and I am hoping you could help me out. I have 16 Plants in 2 different beds and I have 3 out of the 16 showing the same strange cured stunned growth. They both seem to be the most severe on the plants closest to the fence. What is strange is that all three are different strains and in 2 separate beds showing almost the identical problem. The first one to show the symptoms yellowed badly before the curling happened. The others showed no yellowing just curled leaves. The Beds are placed perpendicular to the fence and the ones closest to the fence in both beds are showing the worst curling. What else is strange is on 2 of the 3 plants the curling is on only 1 of the "V" branches the other side of the same plant is growing just fine. I am using a homemade super soil in raised beds and all the plants are on a string trellis grown in a "V" pattern.

See the attached pics. I am not sure if this is a dieses, nutrient deficiency or pest.
