Inspect for Pests and Diseases
Look for signs of pests and diseases, such as the presence of insect pests, chewed leaves and foliar diseases. One diseased plant can swiftly infect all the other ones since they are so close to each other. Remove any sick plants immediately. Because plants grown hydroponically don't have to spend their energy trying to find food, they can spend more time growing. This helps them to be healthier and stronger because they can use some of that energy to fight off diseases. Since the leaves of the plants never get wet unless it rains, they're much less likely to get leaf fungus, mildew and mold.
Even though hydroponic plants are good at fighting off diseases, they still have to fight pests. Even if it's hydroponic, insects and caterpillars can nevertheless find a way into the garden. Pick off and dispose of any bugs you see.
