Mixing Instructions

1

Start with Clean Water

Use room temperature water (18-22°C / 65-72°F) in a clean container. For best results, use filtered or dechlorinated water.

2

Add PuurNitro First

Add the recommended amount of PuurNitro to your water and stir thoroughly for 30 seconds. This provides the nitrogen foundation for plant growth.

3

Add PuurPhos Second

After PuurNitro is mixed, add PuurPhos and stir thoroughly for 30 seconds. This provides phosphorus for root and flower development.

4

Add PuurK Third

After PuurPhos is mixed, add PuurK and stir thoroughly for 30 seconds. This provides potassium for flowering and plant strength.

5

Add PuurCalMag Fourth

After PuurK is mixed, add PuurCalMag and stir thoroughly. This prevents calcium and magnesium deficiencies.

6

Add PuurBalance Last

Finally, add PuurBalance and stir thoroughly. This micronutrient blend enhances uptake of all other nutrients. Wait 1-2 minutes after mixing.

7

Check pH

Target pH: 6.2-6.8 for soil and soilless mediums. Organic nutrients naturally buffer pH, but always verify before feeding.

8

Apply to Plants

Feed once per week until you see 10-20% runoff. Water with plain pH'd water between nutrient feedings to prevent salt buildup.
