Add nutes to distilled h2o right before watering, and do not keep the extra. Pour it on a houseplant or a bush outside, they aren’t pre-mixed for a reason. **Q: Is this a foliar spray or use as a root drench?** A: Root drench. Shake well before use. Mix 1 tsp (5 mL) per gallon (4 L) of water. Begin use just before bud development. Continue use as needed, not more than once per week. Maintain a pH range of 5.6 – 6.8. A pH outside this range can impact the availability of calcium and magnesium. **Q: Can this be use with coco?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works! *by H***. on 10 July 2026* Love this stuff it does help word off the blossom, especially with the crazy weather we’ve been having. ### ⭐⭐⭐⭐⭐ My plants love it *by K***R on 7 July 2026* My plants love it.
