No, you do not have to test the pH of the water before using Fertilome Triple Action unless your water tends to be more alkaline or acidic. You may need to add a pH buffer.
Fertilome Triple Action with 70% Neem Oil could harm Hibiscus blossoms because of its sensitive tissues. It would be recommended to apply at the cooler points of the day. Also, on a day that is less windy to help prevent drifting on the Hibiscus.
Fertilome Triple Action with 70% Neem Oil contains both neem oil and pyrethrins, a non-selective insecticide. This product will affect any insects contacted by the direct spray due to the oil and the pyrethrins, so you would want to avoid spraying when pollinators are present. The neem oil alone acts primarily on larval stages of ornamental pests that ingest the active ingredient while feeding, so an option without the pyrethrins would be Bonide Neem Oil Concentrate. Keep in mind that oils may still act as a suffocant to non-target pests.
The Fertilome Triple Action is labeled to be used on any edible plant and non edible plants. It has not specifically been tested for use on Cannibis plants so we cannot say for certain that it would be okay and you may want to check with other local cannabis growers in your area regarding the use of the product on your plants.
The dilution rate is 1 fl. oz. of Fertilome Triple Action with Neem Oil per gallon of water. Please see the product label for complete application instructions.
