Help: I have grown tomatoes before in my hydroponic NFT set-up with no problems. The plants are about six feet high, loaded with flowers and different stages of tomato fruit. The leaves looked healthy and happy a week ago and now suddenly they are soft and droopy as though they did not have enough water.
The pH and EC of the nutrient is within range and the nutrient flow is around 2 litres per minute.
