Description
Ideal for hobbyists or more serious growers alike, Plant Magic PK 13/14 helps deliver larger, tastier yields.
- Larger, more abundant fruit
- Increases crop yield and quality
- Promotes healthy, faster growth
- Can be used with any nutrient range, crop type, and both hard or soft water
Containing the vital phosphorous and potassium plants need from the mid-bloom onwards, the high potassium content delivers more colourful fruit, and phosphorous enables efficient plant energy management allowing for bigger, increased crop yields. The increased sugar production means tastier, more aromatic fruits.
How to use PK 13/14:
- Shake well before use.
- Apply at a dilution rate of 0.5-2ml per litre from around the start of week 4 in the bloom phase until the stage.
- Please refer to the feed schedule for more information (see downloads below).
Best Practices:
- Use clean measuring instruments - do not put anything into the bottle.
- Optimal pH range: 5.5 - 6.2
- For best results, monitor EC regularly and adjust accordingly based on crop type and growth stage.
- Store away from direct sunlight, closed in its original packaging between 5°C and 25°C.
- Once open, use within 6 months for best results. Use within 2 years of production date (see cap or bottle).
