Strange top leaf growth

[elight]

Another season in Central Florida, another new disease/pest to battle. This seems to be affecting a number of my plants throughout the garden - both in raised beds and containers. The top leaves (new growth) appears very thin and curled, with skinny stems. The plants had started out great with the warm spring weather and zero precipitation we've had the past few months. I use a fertilizer injector on a drip system (at first, Foliage-Pro 9-3-6, and for the past few weeks since fruit set, Texas Tomato Food). Everything is pruned to a single stem on strings with tomato clips (first time trying).

Any thoughts on what this could be?
