The General Hydroponics Flora Series is a liquid nutrient system formulated for growing and flowering cannabis plants that can be customized for different stages of plant growth. It consists of three formulas: FloraMicro, FloraBloom, and FloraGro. FloraMicro provides nitrogen, calcium, and trace minerals. FloraBloom supplies phosphorus, potassium, magnesium, and sulfate. FloraGro supports vegetative growth with nitrogen, potassium, magnesium, and sulfate. To use the Flora Series, you need to follow the feeding chart and schedule provided by General Hydroponics. For autoflowering plants grown in soil, you can use a lower concentration of nutrients and a less frequent feeding schedule than for other plants.
