1. Small plants and cuttings: For plants in early growth stages, add 0.25 grams of Powder Feeding Long Flowering per liter of water. Mix well to ensure even distribution of nutrients.
2. Growth phase: When your plants are in the growth phase, increase the dose to 0.5 grams per liter of water. This will provide the plants with the additional nutrients needed for healthy development.
3. Flowering phase: During the flowering phase, increase the dose to 1 gram per liter of water. This increase in nutrient concentration will help promote bud formation and maximize resin production.
4. Outdoor plants under extreme light conditions: If you are growing your plants outdoors and they are exposed to full sun or extreme light conditions (more than 1000 watts of light), you can increase the dose to 1.5 grams per liter of water. This will ensure that the plants receive the additional nutrients needed to thrive in high light intensity conditions.
It is important to note that the recommended doses are based on the assumption that the water used for the mix has an original electrical conductivity (EC) of 0.0.
If your water has a different EC, it is important to adjust the amounts of Powder Feeding Long Flowering accordingly to maintain the proper nutrient balance.
Finally, keep in mind that it is advisable to stop applying any type of fertilizer during the last two weeks before harvest. This helps avoid unwanted flavors in the buds and ensures a high-quality harvest. Follow these instructions and you can enjoy abundant and top-quality harvests with Powder Feeding Long Flowering from Green House.
