Stickanswered grow question 6 years ago Hi there! What’s the nutrients brand? They must have a schedule and basically you can divide their numbers by 2 or 3, see how the plant reacts and adjust if necessary. Usually 2oz / gal should be fine. This kind of nutrients is known to work best as a foliage spray. Spray directly on leaves once or twice a week, when the light is off. Happy growing!
