EZ-Gro GA3 Prime contains gibberellic acid (GA), a very potent plant growth regulator whose natural occurrence in plants controls their development. GA promotes plant and flower growth. Applications of very low concentrations can have a profound effect while too much will have the opposite effect. Excessive application rates may result in undesirable stem elongation. Do not use more than the recommended rates. Do not mix more than required at time of application. Evaluate the effects of EZ-Gro GA3 Prime on a small number of plants prior to application on a widespread basis.
