After planting, feed with the liquid nutrients and toner by mixing with 16 oz of water and spraying the plant leaves thoroughly. Pour any remaining nutrient mixture on the soil. Water at the surface of the soil, rather than directly on the leaves.
When heat and hours of sunlight increase in the summer, it's important to water consistently. In general, early morning or early evening is the optimal time to water your garden. This gives your plants time to absorb the water before the heat of the day kicks in, and also allows excess water on the plant to evaporate quickly so your garden is not vulnerable to fungus.
A good rule of thumb is to check the first inch or so of the soil and if it feels dry, it is time to water.
