CANNABIS CULTURE – Ganja Guru Ed Rosenthal explains how to take care of your plants in the heat.
Question: During the last couple of weeks I over-watered outside for two weeks during a heat wave that hit temperatures over 105° F (41° C). Besides letting the ground dry out, do you recommend adding anything when I water now?

Ed Rosenthal: When you overwatered, the irrigation water seeped into the ground and headed downward, carrying available soluble nutrients with it. The soil may be depleted of nutrients, so soluble fertilizers should be added to the irrigation water. The main nutrient that was probably lost was nitrogen. If the plants are still in the vegetative stage, make sure that your water-soluble nutrients have a high ratio of N.
