I've used a plastic tube and a water storage tank to drip water tomatoes, peppers, and a variety of other vegetables.

The water warmed up in the tank, and I just poked a pin into the tube where I wanted the water - I checked regularly when first setting up, and re pinned the holes where necessary as they tended to seal up - it was quite narrow transparent tubing.

I used to put a little fertiliser in the tank a couple of times a week.

The curling of leaves is a reaction to drought, it created a micro climate to reduce water loss by transpiration, but also reduces photosynthesis.

If you have hot sun all day you could try creating a little shade using netting, which can be removed if the light is not so fierce, or doubled up if you get clear skies.
