Hey growmies. I've got 3 autos and they just popped the soil a week ago. I picked up the Green Planet Nutrients GP3 starter kit today and was wondering if anyone has had experience with this kit and running autos. Thanks
Using new-quality soil you should have a nutrient starter charge in the soil. When your plants get a few leaves and the stem turns woody you can start feeding. I would start with 1/2 the manufactures recommendations and raise it if needed. I would do a pour thru of the new soil before planting and test the EC. After finding the EC I would maintain the same EC numbers with fertilizer through out the grow.
