There is a Leaf Curl Disease, but leaves and branches curl when a plant is stressed, could be from irregular watering, cool weather, I don't see a sign quite yet that the manures you added had come from animals that were fed hay with a weed preventive, they would be stunted and curled like that, or more so, as those pasture weed preventives go straight thru a cow and back into the ground, there are pics of what those do to vegetables on the internet for comparison. The yellowing does look like a fertilizer imbalance, NPK should be lower on the N scale, but remember P is a salt, and really doesn't need to be higher than twice the N number. Depending on your soil I wouldn't go for higher NPK than perhaps a 6-8-8, or even 3-4-4. I like granular because it works into soil and feeds the plant a bit more even. I do feed a bit more at a time than recommended tho. Too much and too high a number on the fertilizer can turn stems woody and they won't take up nutrition. Also, what varieties are you growing, and are they determinates or indeterminates?
